Why this bike wins here

Watts of the Wild is rolling, with 7.4 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 7.3 s faster than the SwissSide HADRON Ultimate 650, but 0.37 kg heavier.

What the terrain rewards, from its climbing alone: aerodynamics against low weight
