Short Giro prologue means new bike for O'Grady
A look at the Wilier Triestina bike that was designed especially for the Giro prologue.
In today?s extremely short Giro d?Italia prologue (1150 meters), Team Cofidis? Stuart O?Grady will ride a Wilier Triestina bike that was designed especially for this event.
The frameset is made of aluminium Scandium (the same material normally used by Team Cofidis) and has been conceived to offer the highest possible level of aerodynamics.
The aerodynamics tests in the S4 wind tunnel in Paris, France took a whole day to value the position of the athlete on the bike and the different adjustments of the saddle, of the handlebar, etc. All the data were analyzed and processed by Mavic software, also taking into account the strength and the direction of the wind, the use of various wheel types, and other mechanical solutions.
Besides the absence of deraileur gearing system (53x14 is the only gear), the special features of this frame are located at the rear part, which is made with the geometry of a track bike: the ratio of the chain-stays has been modified from 135mm to 120 mm.
The track wheels are fixed to the frame by bolts. The bike also features special tubular tyres that are light and offer low rolling resistance.
The front brake is ?hidden? behind the fork and the pedal crank set is extremely stiff and narrow, to reduce the frontal area of the bike ? further enhancing aerodynamics.
The cockpit features ITM's newly introduced Nivola TT handlebars (all carbon, of course) and Vision brake levers. Will this bike help Stuart O'Grady in his quest for the maglia rosa? Stay tuned to Roadcycling.com to find out.
