Giant sharpens the Anthem for '09
Giant has lightened up its Anthem
cross-country race machine

Giant Bicycles has revised its Anthem short-travel cross-country race
platform for 2009, giving it more travel and more versatile handling but
also markedly less weight.
The Maestro multi-link rear end now boasts 100mm of travel and the unique
'co-pivot' arrangement originally introduced on the Trance X and Reign
(the lower shock eyelet and forward lower link share the same pivot).
Total frame weight has dropped 185g yet new 3D-forged two-piece rocker
links also gives the Anthem X a five percent increase in pedaling and
frame stiffness, according to Giant.
The original Anthem's ultra-fast handling reflexes have been toned down
a bit as well. The head tube angle is now a slightly more sedate 71° and
fork travel has been increased to 100mm across the board (current Anthems
are fitted with 80mm or 100mm forks, depending on locale).
The original Anthem was somewhat of a pet project for team rider Adam
Craig, a US Olympian whose technical skills are well documented. This
new machine continues the trend but with a slightly new focus and new
nickname: 'Ultimate Vermont Domination', in reference to the demanding
course at Mt. Snow.
"Over the last year I've been working on a variety of bike development
projects for Giant," said Craig via his periodic email updates. "One in
particular had a definite (personal) goal from day one. Ultimate Vermont
Domination. With the combination of extra travel and a touch slacker angles
than those found on the razor sharp Anthem Advanced, you can take the
irresponsibility of your (cross country race) riding to a whole new level."
Cervélo announces voluntary recall of Wolf SL forks

Cervélo is voluntarily recalling all True Temper Wolf SL carbon forks
on Cervélo bikes after finding a potential safety issue involving the
fork steerer which can crack and eventually break during normal use, potentially
causing serious injuries. Cervélo says the specific problem was identified
in the field and not through initial US and international standard testing
(which the fork passed). The company has discontinued the use of the True
Temper Wolf SL carbon fork.
Affected forks have a clear coating over black painted carbon fibre,
with the words "Wolf Superlite" and related logo just below the crown
on each fork leg, plus the letters "SL" on each leg above the fork blade
dropouts. There will also be is a "True Temper CRT™" logo on the inside
of both fork legs.
This recall is applied to Wolf SL forks only; the Wolf TT and Wolf CL
forks are not included.
Recalled forks could have been included on the following bicycle models:
- R3 SL
- Soloist Carbon
- Soloist Carbon SL (SLC-SL)
- Certain P3 Carbon framesets and complete bicycles
Affected consumers are urged to immediately discontinue using their Wolf
SL and to contact your authorised Cervélo dealer to have a free replacement
fork installed. Cervélo will replace recalled forks free of charge (including
both parts and labour) with either the 3T Funda Pro or Easton EC90SLX;
all US consumers will receive the 3T Funda Pro only.

Chris King tests the waters with 15mm QR and revisits bottom brackets
Get ready for a new 15QR-compatible
front hub front Chris King.

The 15mm quick-release thru-axle system pioneered by Shimano and Fox
Racing Shox continues to build steam and has recently earned a notable
mark of credibility. Chris King, the headset and hub company renowned
for its reluctance to adopt new and unproven 'standards', recently showed
off some prototype 15QR hubs at last month's Downieville Classic.
According to Chris King's Chris DiStefano, the company has been testing
the system in conjunction with Fox Racing Shox "for some time now" and
after the positive reception at Downieville, it confirmed that it will
definitely introduce some type of 15QR hub for the '09 model year.
Final specifications have yet to be determined but the hub will almost
certainly be based on either Chris King's existing 9mm QR or 20mm thru-axle
hub shell… or possibly both. DiStefano stressed that one of Chris King's
paramount goals is maintaining compatibility such that existing 9mm or
20mm Chris King front hub owners will be able to switch to the 15QR system
if they want with just an axle swap. It's probably unlikely that current
20mm users will want to step down to 15QR but the idea should be appealing
to 9mm users as that route would yield the lighter system weight (which
is one of 15QR's main purported benefits).
In addition, Chris King also unveiled prototype rear mountain bike disc
hub to work with either 10mm or 12mm thru-axles. DiStefano says the new
hubs will be available as complete units and as conversion sets around
the end of summer or early fall.
Chris King also renewed our hopes that we might yet eventually see the
heralded logo on a bottom bracket given the appearance of an external-bearing
prototype mated to a Shimano crankset.
"We've been asked for so long to make one that we figured we'd do some
bearing testing down there and do some investigation while we're out testing
hubs," said DiStefano. The company offered up no additional details nor
would it confirm whether or not it's slated for production. Regardless,
it's likely a safe bet that the bearing quality will be top-notch. Keep
your fingers crossed.
Giro eyewear range to grow for '09

new Pop Top technology

Giro's range of cycling-specific eyewear will feature four models for
2009, including updated versions of its existing Havik and Semi, a new
interchangeable model, and even a mountain bike-specific goggle.
The all-new Filter will incorporate Giro's novel 'Pop Top' lens interchange
technology which it first previewed in 2007. A locking cam is cleanly
integrated into the frame and allows for easy lens swapping while minimizing
both applied force and surface contact. The Filter will also be Rx-ready
and will carry a retail price range of US$159-219 depending on lens option.
A hard case with space for extra lenses will be included as well.
Giro will carry over the popular Havik and Semi but will add new Havik
Full and Semi Full variants fitted with larger lenses for more coverage.
The Havik and Havik Full will range in price from US$139-169 and the Semi
and Semi Full will command US$99-149.
All Havik, Semi and Filter models will feature Giro's Super Fit shaping
for a no-interference fit with most helmets, Zeiss-certified optics (8-base
on the Semi and Filter; 7-base on the Havik), and Wind Tunnel ventilated
The Score MTB goggle is based on Giro's similarly named snow-specific
model but adds tear-off compatibility for muddy conditions. As with the
standard Score, the Score MTB will use a cylindrical polycarbonate lens,
a vented flexible polyurethane frame, a silicone-backed strap, and Super
Fit shaping for a 'no gap' fit with most helmets. Giro will offer the
Score MTB in two frame/strap colors and two lens tints. Retail price is
a reasonable US$60; a 10-pack of tear-offs will add another US$12.
Giro has also announced that it will venture into the cycling glove market
for 2009. We'll provide more details as they become available.

Northwave has taken the lessons learned from its road-going Aerlite series
and applied them to the off-road side for 2009. As the name suggests,
the new Aerlite SBS MTB and Aerlite SBS Carbon MTB feature much improved
ventilation thanks to the liberal use of open mesh plus Northwave's effective
Both models will also borrow the 'Ultra Y' heel fit system, which includes
a polyurethane cage around the heel, an injection molded heel counter,
Northwave's SBS buckle and a newly adjustable ASR2 (Ankle Strap Retention)
main strap with an EVA foam pad.
Naturally, Northwave also fits the sole with an aggressive tread and
optional toe spikes.
