Why this bike wins here

Downtown Dolphin is rolling, with 8.7 m of climbing per kilometre, the kind of course where aerodynamics usually counts for clearly more than low weight.

Disc or regular wheels is a close call: the Cadex 4-Spoke/Disc is 0.32 s faster than the SwissSide HADRON Ultimate 650, but 0.37 kg heavier.
