Why this bike wins here
23rd St. is mountainous, with 100.0 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.
What the terrain rewards, from its climbing alone: aerodynamics against low weight

The course
Mapped surfaces; the shares describe the timed segment.

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 .
