Why this bike wins here

Radio Rendezvous is mountainous, with 35.9 m of climbing per kilometre, the kind of course where low weight usually counts for far more than aerodynamics. The Specialized Aethos S-Works is a climbing frame, the kind of frame that terrain favours. Disc or regular wheels is a close call: the Princeton Wake 6560 White is 8.9 s faster than the Shimano DURA-ACE C99 + Disc here, and 0.52 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 .
