Why this bike wins here

Achterbahn is hilly, with 20.9 m of climbing per kilometre, the kind of course where low weight usually counts for clearly more than aerodynamics. The Specialized S-Works Tarmac SL9 is an all-round frame. Disc or regular wheels is a close call: the Princeton Wake 6560 White is 6.7 s faster than the Cadex 4-Spoke/Disc here, and 0.55 kg lighter.

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 .
