Why this bike wins here

Petit Boucle is rolling, with 7.9 m of climbing per kilometre, the kind of course where aerodynamics usually counts for far more than low weight. The Specialized S-Works Tarmac SL9 is an all-round frame. Disc or regular wheels is a close call: the Cadex 4-Spoke/Disc is 10 s faster than the SwissSide HADRON Ultimate 650, but 0.37 kg heavier.
