Why this bike wins here
Leith Hill is mountainous, with 68.0 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.

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 .
