The Campagnolo Comp Ultra 11-Speed OT Crankset is the result of an innovative urge from Campagnolo and pushes the boundaries of what is possible at this moment. The result of this is the Comp Ultra series, where all of the already excellent crankarms are made even better. The newly designed crank arm and large-diameter axle ensure 5% more stiffness compared to the existing Super Record, along with a 10% improved weight-to-stiffness ratio. In short, the Comp Ultra 11s crankset is stiffer, lighter, and more efficient than its predecessor. The new Over-Torque series of cranksets has been tested and validated at fatigue levels over ten times higher than current regulations require. Crank Material: Full-carbon unidirectional/multidirectional cranks. Light alloy fixing bolts. 4 pins on the large chainring with new shifting profile. Chainrings with hard anodization treatment. Integrated aluminum Over-TorqueT axle. Light alloy fixing bolts and nuts. Special dedicated steel bearings.
