Campagnolo's updated 11-speed alloy Centaur drivetrain offers top quality technology and performance for endurance riding. This chainset features a four-arm spider with independent bolt circles for increased rigidity. It is available in 36/52 and 50/34 tooth combinations. The crankset utilizes Campagnolo’s Ultra Torque BB-axle system, which allows for low profile crank arms and improved rigidity by positioning bearings as far outboard as possible. This makes it a lightweight and high-performance component, similar to top-of-the-range models.
