The SRAM XX1 GXP Crankset launched a "1x" revolution in mountain bikes when it was first introduced--and has taken the MTB world by storm. Developed for maximum chain control, each tooth's thickness is precisely CNC-machined to support the chain's inner and outer links perfectly. Additional chain rings (items 50-0679 and 50-0682) allow you to tune your gear range and match your terrain, wheel size and riding style.

Each X-Sync chain ring fits a single, universal spider, allowing you to change rings without removing the lightweight carbon crank arm. New tooth profile alternates thickness by inner and outer links, providing maximum chain control. The BB30 bottom bracket optimizes bearing load and power transfer while minimizing wear.

  • BB30 bottom bracket improves stiffness and power transfer
  • Carbon arms with forged aluminum spider
  • New spider design allows for easier ring changes
  • CNC-machined ring to be exactly in sync with the XX1 chain
  • Weighs a scant 650g
  • 175mm arm length
