Race Face Cinch (BOOST)

RaceFace Cinch BOOST Narrow wide chainrings are specially designed for 1×9, 1×10, 1×11 and 1x12 systems and perfectly fitting the RaceFace Cinch cranckset systems.

  • Narrow wide system : thanks to the variable thickness of the teeth, the chain is hold from dropping even in rough sections!

  • Smooth spinning compared to a classic chainring thanks to the special design of the teeth profile.

  • Increased chain retention during strong jolts thanks to the improved teeth height.

  • Mud evacuation system for a top performance whatever is the weather.

  • Gain 150 to 400 grams on your bicycle weight when going from a classic configuration (with front derailleur and chain guide) to a single front chainring made by Amber Bikes.

  • Made from hard wearing aluminum alloy.
