For racing against the clock, nothing beats a disc rear wheel for aerodynamic efficiency. The Metron TTW is Vision's carbon disc for triathlon and time trial bikes running disc brakes, built light for quick acceleration and sleek to cut drag.

Highlights

  • Full carbon disc rear wheel with a tubeless-ready clincher rim
  • Vision PRS rear hub with a 17 mm axle
  • Four sealed chromoly steel cartridge bearings
  • Centerlock rotor mount
  • Alloy freehub, Shimano HG or SRAM XDR
  • Grey graphics

Speed for triathlon and time trial

The rim and covers are unidirectional carbon for high stiffness at a low weight, and Vision lists the wheel at 1,008 g. It is covered by Vision's Metron lifetime rim warranty for the original owner.

Compatibility & fit

This is one rear wheel, sold on its own, for disc brake frames with Centerlock rotors. Pair it with a deep front such as the Metron 91. Choose the freehub that matches your cassette: Vision lists Shimano 10 to 12-speed and SRAM XDR. Check that your frame, race rules and conditions suit a disc wheel before you buy. Our workshop can fit your tyre, set it up tubeless and move your cassette and rotor across.
