Why this bike wins here

Castle Crit is rolling, with 12.4 m of climbing per kilometre, the kind of course where aerodynamics usually counts for clearly 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 0.06 s faster than the Princeton Wake 6560 White, but 0.55 kg heavier.
