OneUp your drivetrain with OneUp's new Narrow Wide Chainring and take your riding to the next level.

  • Aggressive crud chamfers for awesome mud shedding performance and extended ring life
  • Reinforced Wide tooth design provides maximum ring durability when run without a bash
  • Narrow-wide teeth prevent unwanted chain drop
  • Perfect chainline with 2mm Shims included with 32T and 34T rings (30T rings have built in offset) for a quieter drivetrain with improved chain wear and best drop performance
  • 30T rings have integrated shims and chainring bolt threads to allow the smallest ring size possible on a 104 BCD crank (loose shims are only included with the 32T-36T sizes)
  • Compatible with 9-12 speed chains, allowing a 1X set up on most any drivetrain.
  • Made from 7075-T6 aluminum alloy

*For 2x crank conversions, shims between the crank and ring get you back to an ideal 49-50mm chainline. For 3x crank conversions, shims under the bolt heads allow reuse of your 3x hardware - No new bolt packs required!


  • Ring Type: Single (anti-chain drop)
  • armxBCD: 4x104mm
  • Weight: 40g (30t), 44g (32t)

Installation:  Align the small bump (small hole on direct mount rings) on the inner edge of the ring with your crank arm
