Fear
I'm a 22 year old female cyclist and I've been competing in road races for
the past three years. Rather than a physical problem, I would call this a mental
problem: FEAR. There are three things which hold me back in cycling: cornering,
downhills (especially twisty ones with potholes) and being in a group larger
than two cyclists. In each of these situations I slow down tremendously feeling
sure I'm going to fall. So in a race with a neutralised start (especially with
a few sharp corners), I'm usually right at the back so that I've lost the race
before we've even started racing!
My question is, is there anything I can do to feel more confident on the bike.
I know I'm quite strong as I tend to do quite well in time trials and hilly
races. But I'm far too in love with my brakes!
Michelle Wood

Dave Palese replies:
The feeling and weakness with skills that you cite are common issues for
many riders.
Skills, like cornering, descending, and riding in a group are improved in
the same way you improve the physical aspects of your riding/racing, you follow
a sensible plan consisting of overload and progression.
The issue that I find most often limits good productive skills training,
is that many athletes are reluctant to practice skills at slow speed, to learn
good technique, before increasing speeds to race like levels.
I look at it this way. If you were going to teach someone to hit a baseball,
would you put them up against a national league pitcher their first time at
the plate? Probably not.
Most athletes struggle for seasons trying to learn paceline and group riding
skills on the Saturday and Sunday hammerfests. This is very often unproductive,
discouraging, and dangerous.
With this in mind, back to your question.
Cornering can be worked alone or in a group. At first you may want to work
alone until you get comfortable. Find a parking lot that is empty on the weekend
or after hours. Use the traffic islands, or some cones to create corners that
you will maneuver around. If you can find a place that you can run into off
a slight downhill, this works well, so you don't have to use a lot of energy
getting up to a moderate speed.
Start by riding in the drops, where you have the most control, and just get
used to leaning the bike over and relaxing as you ride smooth through the
turns. Slowly increase your speed over time. Look at the line you want to
follow through the turn and not the patch of road directly in front of you.
When you are working with other riders, practice following others getting
more and more comfortable riding tighter to the wheel in front of you. In
criteriums, corners and your ability to ride through them efficiently is a
big factor in how well you will perform in those races. The less distance
and momentum you lose in the corners, the less energy you will need to use
to hold you position.
As you cornering improves and you become more comfortable on your twisty
descents. Some people are better descenders than others. To descend fast off
of big mountains or even big hills, take a certain mind set. The best you
can do is limit your loses and make up the difference with your strengths,
whatever they may be.
The key is to take the time to work these skills in a productive way. If
you do, even at the expense of a hard interval session, for just a few weeks,
you'll see improved performance I am sure.
Kim Morrow replies:
Dave offered some great advice. Let me add briefly to his comments.
Each one of us, as cyclist, have a tendency to prefer certain types of races
over others. For example, you may prefer time trials and road races because
these are enjoyable to you and fit your strengths. Others may prefer technical,
aggressive criteriums with tricky corners. It is normal to have a natural
bent toward a particular type/style of racing.
But, what is important for us to do as cyclist is to spend time improving
our weak areas. For some of us, this may mean working on technical skills
such as cornering, bike handling, descending, etc. For others, this may mean
focused attention on improving our time trialing abilities with specific TT
workouts. The key is to set aside time in our training schedules so that we
are able to specifically address these weak areas. We ALL have weak areas.
But, we can improve on them.
A great way to improve your cornering is to practice following an experienced
rider thru the turns, both during the week in training, and in a race situation.
First of all (when practicing), take the corners at a slower speed so that
you understand the fundamentals of cornering. Continue to progress until you
feel confident taking them at race pace. Confidence comes through practice
and preparation. The more you practice these skills, the more confident you
will become. The next step is to test them out in a race situation. The more
races you enter, the more experience you will have. The more experience you
have, the more confident you will become.
Being afraid is not uncommon. Sometimes, however, we just need to jump in
there and go for it, even if we are afraid.
I'll bet if you practice these skills faithfully and consistently, that you
will look back in one year's time and see great improvement!
What kind of carbs?
I am 42 year old female recreational rider. Always working to improve my speed.
You have so many articles talking about consuming carbs for fuel, well okay,
but what kind of carbs? What kind foods should they come from, fruit, pasta,
vegetables? Or how much of each if the answer is all of the sources.
I mean really, given the choice I'd like all of mine from ice cream but I know
better and would like to make smart choices.
Pam Hinton replies:
If you want to improve your speed, you don’t necessarily need to dine with
faster people, you want to ride with them. But making those smart choices
you mentioned will help. So here’s the deal on carbs. The word carbohydrate
is a broad term that refers to substances in food that can be broken down
into single sugar molecules (monosaccharides). The most common forms of dietary
carbohydrates are starch, sucrose, lactose, fructose, glucose, and indigestible
fiber. Starch, sometimes referred to as “complex carbohydrate,” is a polysaccharide,
which is many sugar (glucose) molecules linked together. Grains, bread, legumes,
fruits and vegetables are sources of complex carbohydrates. The terms “simple
carbohydrates” and “sugars” refer to carbohydrates that are made up of one
or two sugar molecules (i.e., the mono- and disaccharides). Glucose, fructose,
and galactose are all monosaccharides. Fructose occurs naturally in honey
and fruit. Galactose results from the breakdown of the sugar found only in
dairy products—lactose. Sucrose (glucose + fructose), more commonly referred
to as table sugar, and lactose (glucose + galactose), which is milk sugar,
are disaccharides.
Carbohydrates differ not only in their complexity, but in their effect on
blood sugar. How carbs affect blood sugar is important for overall health,
fueling muscle during exercise, and replenishing glycogen stores post-exercise.
The effect of a food on blood glucose levels depends on the type and amount
of carbohydrate in the food and on how quickly that carbohydrate can be digested
and absorbed. Some foods will cause a rapid increase in blood glucose levels,
while others produce a slower and more prolonged rise. Scientists use the
glycemic index (GI) to quantify the effect of a food on blood glucose and
to make comparisons among foods. The GI is defined as the increase in blood
glucose concentration above baseline during the 2 hours after eating a test
food relative to the response to glucose for an equivalent amount of carbohydrate.
The glycemic response to glucose is set at 100 and the glycemic index for
all other foods is less than 100. Foods that have rapidly-digested carbohydrate
and contain glucose will have the highest glycemic indices. For example, Gatorade
has a GI of 80. Foods containing polysaccharides take longer to digest and
have lower GI values. For example, the GI of bananas is 50 and the GI for
lentils is 30. Refined grains have higher GIs than unrefined varieties. White
bread has a GI of 75 and whole wheat bread has a GI of 50. (A list of the
GI for 750 foods is found in the American Journal of Clinical Nutrition 76:5-56,
2002.)
For overall health, most dietary carbohydrate should come from unrefined
whole grains, legumes, and fresh fruits and vegetables. Unrefined grains are
superior to refined varieties because they provide more fiber and vitamins.
Unrefined grains also have lower GIs, which may reduce the risk of non-insulin
dependent (type II) diabetes. High GI foods may contribute to insulin resistance
because the rapid increase in blood glucose levels after eating these foods
stimulates a greater insulin response than lower GI foods. Although somewhat
controversial, there is evidence that high GI foods contribute to elevated
blood triglycerides (fats), which is a risk factor for heart disease. Fresh
fruits and vegetables are superior to canned produce because the amounts of
vitamins, fiber, and potassium in the fresh varieties are greater. Plant foods
also contain compounds other than vitamins and minerals, sometimes referred
to as phytochemicals, that have health benefits. For example, red grapes contain
resveratol, a compound concentrated in the grape skin and seeds, which acts
as an anti-oxidant, anti-inflammatory, and anti-coagulant. In general, the
phytochemical content is reduced by food processing such as heating or irradiation.
During exercise and post-exercise, the carbohydrate story is different. In
these circumstances, where elevating blood glucose levels quickly is an advantage,
high GI foods are recommended. During prolonged exercise, depletion of glycogen
stores is associated with the onset of fatigue. By consuming high GI foods
during exercise, fatigue may be delayed by providing the body with a glucose
supply that is readily available. Immediately following prolonged exercise
(2-3 hours), the goal is to replenish glycogen stores so that you will be
ready to train again the next day. Insulin secretion is needed for glycogen
synthesis to take place because it increases glucose uptake into the muscle
and activates the process of glycogen synthesis by stimulating the enzyme
glycogen synthase. So post-exercise, the greater insulin secretion associated
with high GI foods is a good thing.
So, Kim, it looks as if you’re in luck with the ice cream dream as long,
that is, as you have it after having done a hard ride with those faster people
we spoke of earlier.
IT band and fixed vs floating cleats
I've had an IT band problem for years. I was recently fitted with orthotics
and in the process was changed to a fixed cleat (new Dura Ace pedals) from floating
(Speedplays). When sitting on a table with my feet hanging loose they point
straight ahead, therefore the cleats were set at 0 degrees. My saddle was also
raised about 3/4 inch.
After 6 weeks with this setup and a lot of riding and racing, my problem has
gone from bad to unbearable. I was told that it would take some time getting
used to the fixed position because of muscle memory so I ignored some minor
pain. However, I can't ride at all now and the pain is almost constant.
I noticed when I sit on a table and bend forward my left foot (problem side)
turns outward. Am I better off going back to a floating system so my foot can
go where it wants instead of torquing my hip and knee? Was the saddle height
increase a contributor?
Dave King
Boston, MA
Steve Hogg replies:
In my view the advice you have been given about using fixed cleats without
freeplay, given your injury history is just plain bad. Freeplay in pedal systems
is cheap insurance against the potential for injury or the exacerbation of
existing injuries. If you don't need rotational movement, you won't use it.
If you are using it, then you need it. Everyone wins with a freeplay cleat.
Judging your foot on pedal angle on a bike by looking at you with legs hanging
from a table is a bad joke. There is only one way to judge an appropriate
foot on pedal angle and that is under reasonable load on your bike!
Stay away from the people whose advice you have followed. The best advice
I can give in the short term is to go back to your Speedplays and old seat
height. The SPD - SLs are a good system, but even the freeplay cleat option
has far less margin for error than your previous Speedplays. Once you are
back to your base state in so far as your left ITB is concerned, have a good,
and I stress above average health professional with a cycling interest or
background, do a full structural assessment of you and get back to me with
the results and we'll proceed from there.
Power based training
I read a great article by Ric Stern on power based training, which I think
was written back in 2002. I am hoping that with the passage of time that more
experience has been gained with power based training to perhaps provide an update
on the web. Thanks for your excellent column.
Bruce Williams
Australia
Ric Stern replies:
Thanks Bruce. Glad you liked the article. The zones that i prescribed in
that article are the zones i still use! What sort of article are you now interested
in? If you're looking for specific advice on how to build a training programme
or for actual coaching advice, it'd be best to contact a coach, such as the
RST group or one of the other coaches here, who would be able to tailor advice
accordingly.
Eddie Monnier replies:
If you're looking for more general reading on power-based training, then
you might want to check out the articles in the
library section of my Web site.
Seatpost with setback
I just wanted to drop you a line regarding seatposts with setback. In a recent
Fitness Q&A response, you mentioned a Time seatpost that's no longer available.
Although I'm not familiar with the Time post, from your answer I gather that
it had significant setback.
I've been using a Titec 'Hell Bent' MTB post on my road bike. Sure it's heavy
(it probably weighs twice as much as some light road posts), but it has more
setback than any other post I've found. It won't help someone who doesn't have
much exposed seatpost, but it's worked for me. And given it's heft, I can't
imagine it ever breaking. I just thought I'd pass it along.
Mitch Kelly
Philadelphia, PA, USA
Steve Hogg replies:
thanks for the positive comments and your interest in seat posts with more
than average set back. For others interested, here is a list of some of the
seat posts that have more than standard set setback. Standard setback I would
define as when the front edge of the seat rail clamp is in line with the centre
of the seat post shaft as viewed from the side. Common examples of standard
posts are Campagnolo and Shimano seat posts. By that standard the below posts
will give you more rearward adjustment.
Kalloy [one piece 'Ritchey' style]: + 10mm
Easton EA 70, EC 70 and EC90: +12mm
American Classic (if the seat is pushed all the way back till the rail bend
meets the abbreviated upper clamp) + 13mm
FSA SL 220 and FSA K Force Carbon: +22mm
TruVativ XR single clamp and TruVativ Team single clamp: +20mm
There are others including a wierdo looking Race Face that has separate tilt
and clamping adjustment and looks at a glance that it has significant extra
setback but it is actually +12mm. Additionally there is the post that Mitch
mentions, though I am not familiar with it.
Tapering
Maybe my last question was expecting too detailed an answer so Ill be more
simple. When tapering many people talk of reducing volume while retaining intensity.
The question is how intense? The answer is often "race pace". For long road
races there is no race pace - there are race paces. Should a variety of intensities
be riden or just the most intense that will not lead to race day fatigue?
Andrew Gannon
Australia
Scott Saifer replies:
I've read with interest the suggestion to maintain intensity while cutting
volume. I have spoken with two Olympic medalist track cyclists who say that
is exactly what they did before their moments of glory: Continue all out sprints
but very few of them.
For my road and MTB cyclists in the ten days before a key race, I actually
have seven days of only short rides with no heart rates above 70% of maximum,
followed by two short days of up to 80% maximum heart rate and a final short
day with a short interval near the lactate threshold. This scheme has yielded
a hand-full of masters national medals, so while it may not be perfect it
apparently doesn't hurt an athlete's chances too much.
Thyroid issues
I have been dealing with a roller coaster thyroid problem for 1.5 years. First
I was hyperthyroid and then fell into hypothyroidism. Since I was not climbing
out of hypothyroidism, I have been on thyroid medicine. I have been taking the
same dose for six months and now, after a recent blood test, I am in a hyperthyroid
state. As an expert mtn. bike racer, I train 12-15 hours a week and am wondering
if my cycling is not allowing my body stabilize. Does anyone have any suggestions?
Meggan Flaherty
Scott Saifer replies:
I also have a history of odd thyroid measurements and lots of bike racing.
Was your hypothyroidism diagnosed by your T4 (Thyroxine) level or your TSH
(thyroid stimulating hormone)? If it was diagnosed by a slightly elevated
TSH level, you may never have actually been hypothyroid. It's common for highly
trained endurance athletes to be euthyoid by T4, but still have elevated TSH.
If you actually had low T4 measured when you were diagnosed as hypothyroid,
then it sounds like you need to adjust your dose downward. That you would
only do with your doctor's supervision of course.
Either way, you need to find a doctor who knows about the effects of exercise
and thyroid hormone levels. Good luck!
Nutrition and base miles
I am a 35 year old, current Cat4 crit racer ready to upgrade to Cat3 in 2005.
I continue to read up on base training at aerobic levels as both preparation
for more specific training periods and the value of burning body fat. My question
may seem a bit unorthodox, but a concern to some low body-fat cyclists. Can
burning too much fat be detrimental? Taking a look at cycling athletes and other
active individuals like myself with already low body fat, about 6-8%, what happens
when you run too low on fat to burn? especially during base miles when the body
is burning on average 80% fat and 20% sugars. If we "carb up" for more intense
training and racing, how should we nutritionally prepare ourselves for the "base"
period.
John Mattio
Pam Hinton replies:
The answer to your question is very simple in a complicated sort of way.
The short answer is don’t worry about running out of fat, carb-up before,
during and after you ride, then eat a balanced diet thereafter. For the long
answer, get out your calculator.
We usually focus on eating enough carbohydrate to replenish glycogen stores,
but your question draws attention to a new, and somewhat controversial, development
in sports nutrition research.
The assumptions of your question are that fuel selection (fatty acids or
glucose) is determined by exercise intensity and that fuel availability may
be limiting. There are four fuel sources available to muscle during exercise:
plasma glucose, muscle glycogen, plasma free fatty acids, and muscle triglycerides.
Plasma glucose is primarily maintained by breakdown of glycogen in the liver.
Free fatty acids in blood come from breakdown and release of triglycerides
(fatty acids plus glycerol) from stored body fat. When we are exercising at
low intensity (25-30% of VO2max, equivalent to walking), most energy (about
90%) is derived from plasma free fatty acids. During exercise of moderate
intensity (65% VO2max, base-mile pace), a greater proportion of energy is
derived from carbohydrate, so the body is getting about half of its energy
from carbs and half from fat. In addition, as exercise intensity increases
from low to moderate, the muscles begin to rely more on the fatty acids stored
within the muscle and less on plasma free fatty acids. At 65% of VO2max, the
rate of total energy expended is about 0.220 kcal per kg of body weight per
minute (equivalent to about 900 kcal per hour for a 70 kg cyclist). Of the
total energy, intramuscular fatty acids provide about 0.050 kcal/kg/min, plasma
free fatty acids 0.060 kcal/kg/min, muscle glycogen 0.080 kcal/kg/min, and
plasma glucose 0.030 kcal/kg/min.
There are two reasons that fat will not become limiting. First, even though
you are very lean, you still have a huge surplus of fatty acids stored for
future use. As an example, let’s assume that you weigh 70 kg and have 6% body
fat. This means that you have 4.2 kg or 4200 g of stored fat. At 9 kcal per
gram of fat, you have 37,800 kcal of stored fat. That’s a lot of hours in
the saddle doing base miles. The second reason that you won’t run of fat for
fuel is that even extremely lean athletes have intramuscular fat stores. In
fact, one adaptation to aerobic training is an increase in intramuscular triglycerides.
Fatty acids stored in the muscle are an important energy source and training
increases these fat stores. Even exhaustive exercise sessions (3 hr at 65%
of VO2max) produce only a 20-25% reduction in intramuscular fat stores.
The controversy arises in how to best replace the fat stored in muscle without
compromising glycogen repletion. High carbohydrate diets, regardless of fat
intake, seem to interfere with the restoration of intramuscular fat stores
to pre-exercise levels. For example, one study of highly-trained cyclists
found that intramuscular fat stores were replenished after 48 hours of a diet
providing 39% of energy as fat and 49% as carbohydrate, but an isoenergetic,
low-fat diet providing 24% of energy as fat and 62% as carbohydrate was ineffective.
Clearly there is a tremendous downside to consuming inadequate carbohydrate
post-exercise. You will not replete your glycogen stores and it is well-established
that pre-exercise glycogen levels are strongly associated with time to fatigue
during endurance exercise. The best practical recommendation is to consume
carbohydrates immediately post-exercise and then a normal diet containing
carbohydrate, protein, and fat thereafter.
Rotated hip
Several of your recent questions remind me of a personal injury I've been dealing
with for a couple years. I've been experiencing recurring weakness in my left
leg. MRI and angiograms have not discovered any obstruction or injury, however
I have demonstrated a tilt and forward rotation of my hip on the left side.
The result of this is loss of power in my left leg, and to date a rather obvious
difference, increase, in hypertrophy on the right side.
Recently you addressed a complaint of Persistent finger numbness which also
reminded me of my own situation; I also have had hand and finger numbness on
the left side too. Would you be able to offer an explanation as to why this
might be recurring, the pelvic tilt,? And could you recommend some form of strength
training and or stretching routine that might help keep my hips from falling
over?
I do not have a leg or foot length discrepancy and I have had a professional
fitting.
I'm pretty sure this situation isn't unique, I think I've heard of a couple
pros who have had a similar problem. To date I've seen a PT who swore I had
a torn hamstring, a vascular surgeon who thought I needed a stent, and I finally
resorted to seeing a rolfer who offered some relief.
Steve Hogg replies:
I am not a health professional but have an interest in developments in various
health specialties. This is because of what I do for a living, but also because
a combination of youthful stupidity and misadventure has caused me to be a
fairly heavy consumer of the services of various health professionals at different
times in my life. I too, have been on what I term the 'medical merry-go-round'.
In my case it took nearly 20 years to find long term solutions to my problems.
Essentially, the orthopaedic/biomechanical model of the way humans function
can only go so far. For the majority of people that is far enough, for some
it is not.
You could do worse than Contact the Carrick Institute www.carrickinstitute.org
and see if you can track down someone relatively near you that has been trained
by them. They have a functional neurological model that satisfactorily explains,
and can resolve long term, postural issues that there is seemingly no explanation
for, or no consistent explanation for.
I doubt that I am the right person to explain this, but essentially, if you
are particularly right or left brain dominant, that can set up neurological
inhibitions or excitations that cause functional and postural changes in the
body that are difficult to address by conventional means.
This may not be you. But if you think it could be, give it a try.
Correcting BMI
I am an avid cyclist, at 53, I still get in between 100 and 150 kilometers
a week... I recently was in a discussion with a few friends, and we started
comparing BMI's and I ended up on the overweight scale compared to my more sedate
friends... since I have been researching this I find out that BMI is not an
accurate indicator, and did find a site that used waist circumference in the
formula, but my BMI is still 25.5... I am 5 foot 9, weigh 172 most days, some
weeks I get as low as 168, I have a 32 inch waist... when I look at my body,
I can see muscle definition in all parts of my body, especially legs, shoulders,
arms and back, I have a little extra "skin" on the abs, and "very small love
handles"... Why am I scoring higher, and what formula can I use to correct the
BMI?
'Dusty One'
Scott Saifer replies:
Try getting a body-fat percentage test instead of looking at your BMI. BMI
is a "fast and dirty" way to identify overweight people, and of course many
very fit athletes score "obese" on BMI scales because BMI does not distinguish
fat from muscle from buckshot left over from a hunting accident. If you have
visible and defined muscle and over most of your body, you are very lean.
Q factor for women
One for Steve Hogg. Considering women’s wider pelvic and angled femur, how
does this effect movement concerning q-factor, cleat placement (rotational,
also) . I can picture this statically but have a problem figuring out what is
happening when movement occurs, i.e. force on hip joint and torque on knee depending
on the q-factor. I think (and this could be way off) that a wider q-factor with
a slight eversion on the pedal would be optimal.
With your experience, what are the indications of the proper q-factor for a
women’s structure?

Steve Hogg replies:
There is such a variety of female humanity and morphology out there, that
it is hard to give you a general answer that is generally applicable. The
wide range of proportion, function/dysfunction, symmetry/asymmetry and technique
that exists in the female population means that individuals have to be treated
on their merits and that I don't have a 'general' approach to positioning
women that in any way differs from my 'general' approach to positioning men.
Women are different to men but the range is so great that I approach the task
of positioning women using the same basic principles that I've talked about
on this site.
The goal is always to improve leverage, improve ability to breathe under
load and promote good control of movement. The means is by stabilising the
pelvis by passive means as much as structure and function allows, unloading
the torso musculature as much as is practicable, and by positioning cleats
[and in many cases modifying foot plant on the pedal] so as to allow a given
rider, male or female, to ride hard without discomfort and avoidable injury.
I understand where you are coming from, but it this is generally only a typical
concern on wide hipped, proportionally short-femured women who have as a result,
a large 'Q' angle, ie, the angle that the upper leg meets the lower leg at
the knee.
Knee circles
I'm 48 years old, 195 cm, 96 kg recreational roadie. My problem is recurring
bouts of ITB soreness which may build up gradually during a ride or appear suddenly.
The bouts may last weeks or a single ride. I do several ITB stretches in a 20
minute stretching routine after most rides and ice the knee after rides as well.
I ride 4 - 5 times a week and the pain seems to occur just as often on light
recovery rides as it does on fast group rides. A dozen years ago I snapped my
right ACL and in the process injured the ilio-tibial band although this last
injury was only picked up months later when I had problems during rehab after
the reconstruction.
Apart from the ITB pain which only appears when riding the knee has generally
been fine since the op. What I have now is a right knee that moves in circles
laterally when riding. The knee moves towards the frame on the up stroke and
away from the frame on the down stroke. I have noticed that I also ride on the
outside of my right foot. When I force the foot flat on the pedal the knee circles
are greatly diminished but the ITB soreness increases immediately.
The advice of my sports physio is to persevere with the stretches/icing/pain
or consider a release op. I haven't heard much good said about the op and anyway
I don't favour surgical solutions unless absolutely necessary. Some months ago
I bought a new, lighter bike and had the shop set it up. I immediately found
the ride to be much more comfortable than my old bike but the ITB problem remains
the same (I was hoping for a change of one sort or another). My searches for
a "cure" have led me down many different paths including one to my local podiatrist
and I now ride with orthotics. I still wear the orthotics but I haven't noticed
much difference.
When the pain hits it can be severe and I have found that riding with my heel
hard down relieves the pain and allows me to get home again. As far as I can
tell my left knee tracks "normally", basically up and down with very little
lateral motion noticeable and no ITB soreness.
Any suggestions?

Steve Hogg replies:
Steve, you are posing a tough question. Obviously finding the root cause
of the issue is the key, and you have been trying to find that out with limited
success. On this site David Fleckenstein or Benoit Nave are the appropriate
people to ask. The only thing that I can contribute is this:
1. The first thing to do is to establish that this is indeed a right side
problem, and not caused by something you are doing on the left side where
you feel no pain. Mount your bike on an indoor trainer, level the bike between
axle centres, and have an observer watch you pedal in a biggish gear at 80
- 85 rpm so that you are working reasonably hard but not sacrificing technique.
You will need your shirt off. What your observer needs to look for is whether
you are dropping your left hip on each pedal downstroke. If you are, and it
is possible rather than likely, then the problems you are having with the
right leg are largely a consequence of what you are doing on the left side.
If this is indeed what is happening, get back to me and I'll give you advice
on how to work around the problem.
If you are not dropping the left hip, you are either not dropping either
hip, or are dropping the right hip.
2. If you are not dropping either hip, it is safe to assume that this is
indeed a right side problem. The potential causes are many and varied but
if, and I stress if this is a consequence of your ACL and ITB injuries then
it is likely that you do not have the ability to extend the right leg as far
with power and control as pre accident. It is probably worth fitting a 3mm
- 5mm spacer underneath the right cleat to ascertain whether this relieves
the problems you have. Sometimes what you describe can be a consequence of
trying to reach too far with one leg. From what you have said about the pressure
on the outside of your foot when you pedal, a medial lift in your right shoe
probably wouldn't go astray either. This would enable you to spread the load
over the whole forefoot, rather than the outside edge and, as you have noted,
bring the knee back to a single plane of movement.
3. If you are dropping the right hip, then the question we have to ask is
why? The answer is commonly overtight hip flexors on that side, and less commonly
asymmetries of pelvic function or measurement. If you are dropping the right
hip, get back to me and I will advise you from there.
New cleats and bike fit
1) I recently changed to new cleats about two weeks ago. I use Look cleats
and have for years, but this time I have noticed some slight pain to the left
and front of the knee cap. Its a dull ache and it seems to go away pretty quick
after I'm done riding. During my rides, I find myself wanting to push my heel
out away from the bike and toe in almost pigeon toe. I tried adjusting the cleat
to allow me to do so, but the cleat is already over as far as it will go on
the shoe. For lack of a better description, with my old worn cleats, my foot
could float over the pedal and I could move around, but with the new one, my
feet are locked in and I can't seem to get comfortable with the left foot. My
right foot does just fine. Any clue as to what is going on and what I can try
to make it better? Will the new cleat eventually "break in" and give me the
float that I had with the old ones?
2) I'm in the market for a new frame this winter and I've been a victim in
the past of a poor fit and obviously would like to avoid that happening again.
We used the Serotta size cycle, dialed in the numbers until I felt comfortable
and voila, instant measurements for a frame. Today, I am the not-so-proud owner
of a rather odd shaped frame. Short of traveling to someone who has the reputation
as a good bike fitter and is equipped to do the job, what should I look for
from my local bike shop in terms of assessing if they can do a good job? How
do you qualify who's got the goods and who doesn't?

Steve Hogg replies:
In answer to your question 1. There are a multitude of possible reasons for
what you are feeling, but given that you had no problems with your old cleats,
here is what I would suggest. On the base of a Look cleat there is a black
rubber pad. When new this can tend to protrude quite a bit, particularly if
the cleat mounting screws are torqued really tight. This means that though
there is freeplay, it is has a 'stiffish' quality. Get a razor blade or Stanley
type knife and trim most of the height from the rubber pad. Trim it back till
it is almost flush with the cleat. This will allow the quality of freeplay
to become just that ' free', and solve the problem. The other thing that occurs
to me is are you using Look branded cleats or some of the clones?
I have noticed that some of the Look clones, particularly Exus brand, are
a much tighter fit in the pedal when new than the Look branded original. If
this is the case, switch back to the Look originals and if necessary, trim
the rubber pad.
Your question 2, and proceeding on the assumption that the retail bike scene
in the US doesn't differ much from what happens here in Australia, I, in your
shoes would travel if necessary to someone who comes well recommended as being
able to do the job. For most bike shops, rider positioning is an 'add on',
rather than a job in, and of itself. Many either can't, or don't wish to spend
the time and effort necessary to solve the positioning puzzle at a high level
of proficiency. Frankly, there is not much incentive for them to go down that
road either. If they do, they will find that most of the commonly bruited
about info is suspect at best, and that production frames have less relevance
to a large portion of humanity than they should. In short, what I'm saying
is that in my view, mass production bicycle frames owe more to keeping unit
costs low than they do to addressing a mid point in the range of human needs
out there. This approach explains why if you pick on any single manufacturers
particular model, you will find almost invariably, that chainstay length,
and fork offset doesn't change from the smallest to largest sizes but seat
tube angle does. This approach is illogical.
If you are spending a reasonable amount of money, you want the best result
for that money. Find the right person. Ideally they should take a structure
and capability based approach to positioning and have enough confidence in
their abilities to design and supply a frame on a money back if not happy
basis.
Dan responded;
I am using clone cleats and I trimmed the rubber pad back last night. I went
out on a short ride and the knee felt great; plenty of play like my old cleats!
I would love to travel to be fitted by a specialist, but I would have a hard
time justifying the expense since I'm buying a production frame in the $1100
to $1400 range. Hopefully armed with more experience and knowledge now than
my first attempt, I can have a reasonable dialogue with some of the shops in
the area and determine who will be the best to work with. One last question
though, you mentioned that chainstay length and fork offset do not change from
one frame size to the next. How much should each one change from one size to
the next and why?
Steve Hogg replies:
I am glad that you got a result with the cleat. It is a problem that I have
seen often.
Your question 2; no production frame by its very nature can hope to fit everyone.
One would like to think though, that each size is designed to address a mid
point in the range of needs for people of an approximate size. This is not
the case. For large manufacturers, the question that a bicycle frame is an
answer to is ' how do we produce large numbers of these at the lowest possible
unit cost without affecting quality of materials or integrity of construction'.
Leaving aside the question of whether the information about appropriate positioning
for humans on a bike that modern production frames are supposedly based on,
is accurate [ and if you've been reading this forum you will know my views
about that], the larger the frame, the further over the rear wheel the rider
is going to sit because of the increased seat height. For instance, check
out a catalogue with detailed frame geometry specs from any large manufacturer.
You will find that the smallest size and largest size have the same chainstay
length. This means that the larger, heavier rider on the 62cm frame is going
to have his [greater] weight further out over the rear axle than the smaller
and likely significantly lighter rider on a 50cm frame. This means that larger
riders have noticeably worse weight distribution over the wheels than smaller
riders. The modern approach to relaxing seat tube angles in larger sizes only
adds to this.
Briefly, the smaller the frame size the shorter the chainstays can be. The
larger the frame the longer the chainstays need to be. Seat tube angles play
a part. The steeper the seat tube angle required, the shorter the chainstays
can be [consistent with the perfect operation of 9/10 speed derailleur gear
systems. 410mm is about as short as you want to go ideally]. The more relaxed
the seat tube angle the longer the chainstays need to be. The higher the handlebars
of a given rider, the longer the chainstays need to be to counter the effects
of unloading the front wheel that this can cause.
Conversely, the lower the bars the shorter the chainstays can be and so on.
Fork offset or rake. It is a rare manufacturer [ there are some] that offers
much range of fork offset across their range. It is cheaper to buy in forks
in one size than in a range of sizes. The only reason that small frames have
steeper seat tube angles than larger frames is that by moving the top of the
seat tube forward [ and hence transferring the riders weight more on to their
genitals and hands, and overloading quads and under utilising glutes and hammies]
is so that they can move the front wheel further forward from the bottom bracket
centre for a given top tube length and avoid toe over lap
Large manufacturers could do this but it would increase their cost base and
put them at a disadvantage against other manufacturers that did not go down
that path.
A large marketing effort would be needed [ more cost ] to make this higher
cost approach successful in the market place. And if a large manufacturer
succeeded in this, they have an 18 month window of opportunity to recover
their higher costs before every competitor is on the same band wagon. I think
I will leave it at that; this is in danger of becoming a treatise. I don't
have a website, but will soon. I have written lengthy articles [15000 -20000
words] about this subject some years ago that I will track down and put on
the site. Once you see the link on my bio on the Forum, have a look for more
detail.
Dan replied:
I like the treatise and you make some valid points, but from my experience
over the last 10 years, 90% of the people I have ridden with are on production
frames. (By production, I mean any frame not made to your exact specifications.)
It is the rare individual that is willing to pop for a $2000 to $3000 custom
made frame and then add another $1500 or so for components. Its hard to justify
the cost when you are a club rider and maybe an aspiring amateur racer and to
top it off, the thought that you could trash it on the first ride is almost
unbearable. So taking into account that the majority of riders have to ride
on what's available, how do you shop for the best frame and how do you evaluate
a frame's geometry to determine if it going to be suitable? For instance, given
a range of sizes, what range of measurements should you be looking for in say
fork rake, seat angle, head tube angle, chainstay length, etc?
Don't get me wrong, I agree with you about the manufacturer's illogical approach
to making frames; however, I've got ride one of them (and so do many others),
and since its unlikely the manufacturers are going to change, I need to do the
best I can with what's available. One last bit, we've never made mention of
specific manufacturers which begs the question - "Are there any manufacturers
making production frames with suitable geometries i.e. those that can address
a midpoint in the range of needs for people of an approximate size." I guess
I'm looking for the lesser of all evils.
I have enjoyed the dialogue and will be looking for that link with great anticipation.
Steve Hogg replies:
Your problem is a common one but given that I know nothing about your size,
structure or capabilities, it is impossible to be definitive. That said, I
want to answer your question. I have data on thousands and thousands of people
who have been happy with my approach to positioning them. I have sold custom
frames with every seat tube angle between 69.5 degrees and 74.5 degrees, and
including those who have not purchased frames from me, recommended a slightly
wider range again, as an ideal . About 85% of those fell into the range between
71 and 72.5 degrees. The further in either direction from that range, the
number of people requiring a really relaxed or really steep drops dramatically.
This is seat tube angles only. In my view, that is the most important frame
dimension because it largely determines how you will bear your weight and
what musculature you will enlist and to what relative degree you will enlist
it.
Proceeding on the assumption that you fit into the Joe Average category,
the best bet out there in the sense that the seat tube angle stays the same
in all sizes, and that the fork offset changes in the smaller frames [ which
is the intellectually honest approach to stock frames] are some models of
Look. The KG 481 SL, KX Light, KG 451 and KG 386 all have 72.5 seat tube angles
in every size. I don't have their current full specs available, but in some
of those I think that the fork offset increases and head tube angle decreases
in the smaller sizes, though I may be wrong in that.
Upper knee pain
I am a 33 year old recreational road rider, 6’1”, 164 pounds. Two years ago,
I had reconstructive knee surgery on my left knee for an ACL tear, in which
a patellar tendon graft from my left knee was used to replace the ACL. After
the surgery, I began riding for rehab. I ride four to five days a week on rolling
terrain. Most rides are after work, about 1 to 1.5 hours (20 to 25 miles), with
longer rides on the weekends (40 to 50 miles).
I have begun to experience moderate pain directly above my left patella, slightly
to the left (or “outside”) of the knee. Of course, it is worse when going up
hills (especially seated), and in pushing larger gears any time. I have no pain
in other parts of the knee, and it does not swell during or after riding. It
does not feel as though there is any rubbing or popping going on; it just feels
moderately painful, and is a nuisance. I would love to eliminate it, and I am
slightly concerned that it may worsen over time.
I made a frame change about three months ago, at which time I replaced a Thomson
straight seat post with a USE Alien set back post, and replaced my 120 mm stem
with a 130. I really like the more stretched out position, as it is more comfortable
for my neck, and it allows me to stay in the saddle longer without discomfort
and/or the beginnings of numbness. The frame change was from a 57 to a 58. I
ride Shimano Dura Ace pedals with float, and use Sidi shoes.
My questions are; what is the most likely physical problem causing the pain,
and what are some suggestions for easing (or hopefully eliminating) the pain?
What parts of the bike or equipment do I need to address?
Thanks in advance for your help.
Steve Hall
Eddie Monnier replies:
It's unclear to me if your pain began only with the recent bike change or
if it preceded that. Pain toward the outside of the knee is often caused by
a cleat angle that sets the toes inward too much. To check to see if this
alleviates the problem, mark the current position of your cleat (fore/after
and angle) and then turn your cleat in a few degrees (yes, turning the cleat
in moves your toes out). In most cases, if your problem is related to cleat
angle, you will notice immediate relief with the cleat correctly repositioned.
If it doesn't help, then return your cleat to its original position. Pain
in the front of the knee is often caused by having the seat too low or too
far forward, so I would check your fore/aft position (see Steve Hogg answers
to previous questions for guidance on this) and your seat height.
Finally, I have noticed some riders experience problems with pedals that
float, although in my experience this is usually under higher volume riding
than you're currently doing. Still, if you've tried everything else without
relief, I would try the limited float Dura-Ace cleat.
Steve Hogg replies:
Do as Eddie has suggested and if the problem is still present, here are some
other things to think about.
1. Are your Dura Ace pedals the SPD - SLs? If so, the range of rotational
movement is less than on other systems that allow freeplay and it is not hard
to get the angle of the cleat wrong.
2. Are you tighter in the hip flexors on the left side? If so this could
be playing a part.
3. Does one leg feel jerkier than the other at the bottom of the pedal stroke?
If so, which one?
4. Does the left knee waver laterally while pedalling?
If need be, get back to me once you have worked your way through Eddie's
suggestions.
Steve Hall responded:
Thanks for your further advice; I have already turned the cleat in a little
to give that a go. In answer to your first question; yes I have the SPD – SL
Dura Ace pedal. I switched to these pedals about a year ago from Time Impacts,
and have been generally happy with them. The knee pain has certainly developed
well after the switch. I definitely have a waver in the left leg through the
pedal stroke (in both legs, actually;) I developed the habit of riding with
my knees pulled inward toward the top tube from watching Chiappucci ride long
ago, as well as because it feels like it brings stronger quad muscles into play.
However, my sense is that this would, if anything, cause the inside of the knee
to become agitated. What do you think? And for what it’s worth, I’m right side
dominant, and obviously, my left leg took quite some time to get back its strength
after the ACL surgery. I definitely have the sense that it is the weaker leg,
and work on evenly distributing the load while I ride - particularly during
the upstroke in the pedal stroke up hills.
Steve Hogg replies:
I have no problem with your knees-in pedaling style providing it comes naturally
to you. Double check your angle of cleat placement. Ride along on a quiet
road putting a bit of effort in, and then coast with the left leg forward.
Twist the heel outwards, is there movement before you hit the stop?
If yes, no problem and repeat the pedaling and coast routine and twist the
heel inwards. Is there movement before you hit the stop?
If yes, cleat angle is not the problem. If no to either, adjust the cleat
so that when your foot is at its natural angle, you have an even range of
movement either side of that point. This can be a bit fiddly on SPD - SLs
simply because with the freeplay cleat, the range of rotation available is
not as great as many other systems.
If you go through that exercise and have no joy, have someone to observe
you from behind and see if you drop the hip of that ' dominant' right leg
that you mention. If you are doing that, the left leg will have to reach further
and will be forced to move laterally as a consequence. If this is the case,
get back to me for a solution.
If you are sitting squarely and not dropping either hip, you may wish to
consider whether you are reaching the bottom of the pedal stroke with the
same power and control as the right. If not, try a 3mm spacer under the left
cleat. Again, if this makes a positive difference, get back to me for more
advice.
Lastly, read the posts of the last 8 weeks or so and make sure that your
seat setback is ok. Too far forward and too far back can also give rise to
knee issues. Check the Cleat
Position questions on July 26 so as to eliminate that as a potential cause.
