VISION PRS 72T/46T Helical Key ROAD

The VISION PRS 72T/46T Helical Key ROAD set is an original spare part for the freewheel system of VISION PRS (Preload Ratchet System) hubs used on selected Metron and SC road wheels. This system uses helical teeth (Helical Ratchet) with 72 and 46 teeth, which provide smooth, quiet and precise engagement without play. Thanks to precise machining and optimised geometry, it offers higher power transfer efficiency and a longer service life.

• Tooth combination 72T / 46T – a high number of teeth = quick response on engagement
• Quiet running thanks to the helical tooth profile (Helical Key)
