Why this bike wins here

Libby Hill After Party is flat, with 4.9 m of climbing per kilometre, the kind of course where aerodynamics usually counts for far more than low weight. The Canyon Aeroad CFR - CANYON//SRAM is an aero frame, the kind of frame that terrain favours. Disc or regular wheels is a close call: the Cadex 4-Spoke/Disc is 6.1 s faster than the SwissSide HADRON Ultimate 650, but 0.37 kg heavier.
