Built to go up and come down fast

Climbing builds prioritize low rotational inertia – shallower rims (35–40mm) and lighter builds reduce the energy needed to accelerate out of corners and over short climbs. Instant-engagement ratchet hubs and stiff Toray rims keep the wheelset stable on steep descents. The collection includes carbon-spoke and DT Swiss builds for riders who want race-ready climbing gear without aero sacrifices on the way down.
