Aluminum crank arms with hollowed out rear surface for weight reduction. Light weight hard anodized alloy chainrings. Utilizes Campagnolo's Ultra-Torque crank system.
- Features Campagnolo X.P.S.S. (eXtreme Performance Shifting System) featuring geometrically optimized chainring teeth. Optimized when mated to a full Campagnolo drivetrain
- Ultra-Torque system have both drive and non-drive side bearings pre-installed
- Double standardized bolt circle diameter allows for use of standard, mid-compact and compact chainrings
- Requires use of Ultra-Torque bottom bracket cups
- Ultra-Torque axles couple together in the middle of the BB shell via a Hirth Joint that self centers the crank. This results in a very light weight and stiff system that transfers power to the pedals without power loss
