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.
Please note, chainring & bottom bracket is NOT included.
New tooth profile alternates thickness by inner and outer links, providing maximum chain control
New spider design allows for easier ring changes
