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.
