Why this bike wins here

The Fan Flats is flat, with 4.0 m of climbing per kilometre, the kind of course where aerodynamics usually counts for far more than low weight. The Cervelo S5 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 1.7 s faster than the SwissSide HADRON Ultimate 650, but 0.37 kg heavier.
