Ratchet rings wear out over time especially if ridden in competition or in inclement weather. A worn ratchet ring can cause the pawls to fail to engage or to slip under load.
They are made of Scandium for extra hardness.
Novatec 27T Pressed Ratchet Rings fit several Novatec hubs and also the BDop R142-11 hub. They are compatible with Shimano/Sram freehubs or Sram XD or Sram XD-R Drivers.
If you’re not sure which ratchet ring you need, see our TECHNICAL CHART for a partial list, or CONTACT US and we’d be happy to help.
