Rogers tests new Time TT rig
World time trial champion Michael Rogers (Quick.Step) has a new weapon
for races against the clock. The Australian has been testing a new frame
from Time at the wind tunnel at Milan's Polytechnic College, and the results
look good, with time claiming a 25 percent improvement in aerodynamics
over the team's previous time trial rigs.

In fact what Time have come up with is what the company calls a 'module'
- frame, fork, seatpost and handlebar, all designed to work together for
maximum aerodynamic benefit.
The new frame - dubbed RXR - started as a prototype back in March when
Time staff and Quick.Step coach Luca Guercilena examined the aerodynamics
of the team's existing equipment just before Milan San Remo. The then-proto
RXR turned out to be substantially more slippery than the team's existing
bikes, and production versions were made for the team.

Quick.Step is due to roll out on the new bikes at the UCI ProTour team
time trial at Eindhoven on June 19, but one or two riders from Time-sponsored
teams appeared to be using the new frames at Wednesday's
time trial stage of the Dauphiné.

Corima rolls out new wheel
Speaking of the Dauphiné, Corima picked Wednesday's time trial to competition-test
a prototype of its new three-spoke carbon fiber time trial wheel, equipping
Alberto Contador of Liberty Seguros with the new hoops.
An official launch is planned for the Tour de France, which implies that
this proto is very close to the final production form. Corima claims that
despite having one spoke fewer, the new wheel is stiffer than its previous
design, as well as being lighter and more aerodynamic. A new form of carbon
fiber is credited with enabling the improvements.

Fulcrum shaves grams
Fulcrum Wheels has announced a significant improvement to its entry-level
Racing 5 wheels. Following a successful Giro, in which riders on Fulcrum
wheels won four stages and spent four days in pink, Fulcrum has switched
from plain 2mm spokes on the Racing 5 to 2/1.8mm butted spokes.
The change saves 90g, according to Fulcrum, so a pair of Racing 5s now
weighs 1,840g - a pretty good weight for a set of all-purpose wheels that
retail for €210 + VAT.

Supplement manufacturer First Endurance has announced the availability
of a single-serve package of its Ultragen recovery product. Formulated
for use immediately after training, when First Endurance claims the body's
muscles "open the door to nutrients".
The single-serve packet is intended for sportspeople to carry to races
or rides so there's no need to lug around a big jar of the stuff.

GPS mount for big bars

The move to 31.8mm clamps for handlebars has left many of us wondering
how we're supposed to mount old stuff such as computers and heart rate
monitors on our handlebars. Mountain bikers who use GPS for back-country
navigation have the same problem, so British company TrackLogs has produced
a mount for fat bars that works with any Garmin GPS unit.
The new mount fits all bars from 25mm to 32mm and is supplied with rubber
strips to tune the fit and protect your handlebar's surface. TrackLogs
claims the new mount is just as secure as the original and points out
that a GPS mounted on the bars has two advantages: you can see it (not
the case if it's stuffed in a bag or pocket) and it can get a consistent
fix on the GPS satellites, improving accuracy and battery life.

Eclipse self-repairing tyres
Swiss company Eclipse has announced a new self-repairing inner tube for
road and mountain bikes. However, instead of filling a tube with sealant
and selling a one-off item, Eclipse is packaging up a kit of sealant,
tube and valve. Why? Because sealants tend to dry with age, and eventually
stop working, something Eclipse says takes 8-12 months with its system.
But rather than throwing the tube away or replacing it, Eclipse allows
you to replenish the sealant.
Eclipse claims its sealant will plug holes up to 1.5mm in road bike tyres
and 2mm in mountain bike tyres, with losses of 1.5 bar and 0.5 bar respectively
before the seal takes effect.
