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 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 lightweight carbon crank arm.
