What's the fastest bike for the Box Hill climb?

Based on our physics model, the Specialized Aethos S-Works with Princeton Wake 6560 White is currently the fastest verified combo for the Box Hill climb in London, finishing in 9:24 (~19.1 km/h).

Dynamic physics model active

Dynamic physics is active. The segment is simulated after a 2km flat warmup so the timed portion starts at realistic speed, matching how a Zwift/Strava segment is actually entered (never from a standing start).

How this recommendation works

Combos are ranked by an estimated time for this segment alone, computed from a simplified physics model (your weight, height & power, the segment's real length/gradient, and each combo's aerodynamic drag and weight) rather than the match score alone. The segment is simulated after a flat warmup so it starts at realistic speed, matching how a real Zwift/Strava segment is entered. Bike frame and wheelset aero/climb ratings come from real ZwiftInsider bot speed-test data where available (look for the 'verified' badge) - otherwise they're a name-based heuristic estimate. None of this is official Zwift telemetry, so treat results as directionally useful, not exact.
