Vision is proud to introduce its very first full carbon wheelset: Metron RS (Racing Series), available in 45 and 60mm rims. Built with full carbon rim and spokes, a larger internal diameter compared to Metron SL (23mm) and the new V-1000 hub with PRS technology, Metron RS is designed to win. Extensive CFD analysis and wind-tunnel testing with the most advanced Vision carbon technology coupled with state-of-the-art manufacturing processes bring this handmade wheel to the next level.

AERODYNAMICSAn ultrafast and stable aero wheel developed through extensive CFD analysis and wind tunnel testing. PRS HUB SYSTEMHelical Clutch ratchet with 72T equals a 5 degree engagement angle. This ends up as 24% faster engagement than the previous Vision 6-pawl and DT 54T/6.6 degree. The PRS increases durability all while reducing loss of power engagement under load.
