Why this bike wins here
Breakaway Brae is hilly, with 20.0 m of climbing per kilometre, the kind of course where low weight usually counts for clearly more than aerodynamics. The Cervelo S5 is an aero frame. Disc or regular wheels is a close call: the Cadex 4-Spoke/Disc is 0.07 s faster than the SwissSide HADRON Ultimate 650, but 0.37 kg heavier.

The course
Surface unverified; road assumed by model; the shares describe the timed segment.
| Surface | Share | Distance | Extra watts |
|---|---|---|---|
| Tarmac | 98.5% | 0.4 km | - |
| Cobbles | 1.5% | 0.0 km | - |
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 .
Dynamic physics model active
Every time below is simulated for your weight, height and power, entered at racing speed rather than from a standing start.
