| Aerodynamics | ||
| Manufacturer aero claims | Berria: 3% less drag (4 W at 50 km/h) in a headwind and 11% less (10 W at 50 km/h) in a crosswind, from wind-tunnel tests at the Politecnico di Milano; the frame, fork and bar together account for the 4 W head-on | Rose says the Shave FF is aerodynamically optimised but publishes wind-tunnel figures only for the Shave FFX (205 W at 45 km/h in TOUR's tunnel) |
