Developed for maximum chain control, each tooth’s thickness is precisely CNC-machined to support the chain’s inner and outer links perfectly. Six available chainrings (28-30-32-34-36-38) allow you to tune your gear range to match your terrain, wheel size and riding style.

Each X-SYNC™ chainring fits a single, universal spider—allowing you to change rings without removing the light-weight carbon crank arm.


  • New tooth profile alternates thickness by inner and outer links, providing maximum chain control
  • New spider design allows for easier ring changes
  • Wide/narrow Q factor cranks for BB30 and GXP
  • Arm Material: Carbon arms with forged aluminum spider
  • Weight: 650 grams
  • Rings: CNC machined rings
  • Bottom Bracket: BB30, GXP (Not included)
  • Q-Factor: wide and narrow
  • Technology Highlight(s): X-SYNC

  • BB30: Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction
  • GXP: GXP’s Gutter Seal design cuts friction, durability and weight—improving both feel and performance
  • X-Sync™: A CNC-machined, “wide tooth, narrow tooth” pattern is repeated around the entire XX1 chainring, perfectly mirroring the 1X11 XX1 specific chain’s inner and outer links for maximum control
