Why this bike wins here

Knickerbocker is hilly, with 16.2 m of climbing per kilometre, the kind of course where aerodynamics usually counts for about as much as low weight. The Specialized S-Works Tarmac SL9 is an all-round frame, the kind of frame that terrain favours. Disc or regular wheels is a close call: the Cadex 4-Spoke/Disc is 2.3 s faster than the SwissSide HADRON Ultimate 650, but 0.37 kg heavier.
