  • without chainring and bb!


    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 chain rings (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™ chain ring fits a single, universal spider—allowing you to change rings without removing the light-weight carbon crank arm.

    • 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.
