IMPORTANT: While placing order, please leave a comment if you need it compatible with a normal chain or 12-speed (incl. Shimano HG+ & SRAM AXS Flattop)

  • 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.
