Product details

Vision Metron TTW PRS: rear wheel for time trial and triathlon

The Vision Metron TTW PRS is a carbon lenticular rear wheel for time trial and triathlon bikes with disc brakes. The rim and fairing carbon construction, based on the Metron 45 SL, is dedicated to aerodynamic efficiency in time trial efforts. The design is developed through CFD analysis and wind tunnel testing.

Hand-built construction and PRS hub system

The wheel is hand-built and combines the carbon structure with an aluminum hub featuring four sealed steel bearings. The 72-point engagement Ratchet PRS system manages power transfer through the aluminum freehub body. The setup includes a rim with a 21 mm internal width and 31 mm external width.

Tubeless setup and drivetrain compatibility

The Tubeless Ready rim allows a tubeless setup. Installation on the bike requires a 12 × 142 mm rear axle and a Center Lock rotor interface. Freehub choice depends on the drivetrain: a Shimano HG version is available for 10, 11, and 12 speeds, and a SRAM XDR version for 12 speeds.
