Why this bike wins here

Eastern Eight is rolling, with 7.9 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 10 s faster than the SwissSide HADRON Ultimate 650, but 0.37 kg heavier.

What the terrain rewards, from its climbing alone: aerodynamics against low weight

Extra watts are what the fastest setup needs to hold its pace on each surface rather than on tarmac, averaged over the ride - they appear once a ranked setup and mapped surface positions are there to simulate .
