Pick your wheel type: Spoked for a Warp 9 spoked wheel, or Forged Tubeless for a Warp 9 forged tubeless wheel. The forged hub takes its own kit.

A rear wheel bearing kit for the Warp 9 115R cush drive hub on 2024-and-older Beta models with the 20mm axle, with what you need to rebuild one rear wheel: the hub bearings, seal, C-clip, distance tube and wheel spacers, plus the bearings and inside spacer for the cush drive sprocket carrier.
