The new carbon Super Record 12x2 speed crankset is lighter on the inside through Campagnolo Hollow Technology, which uses the Ultra Torque bracket system with a titanium axle to transfer all of the force to the drivetrain. The use of ceramic Cult bearings leads to obtaining the smooth ride that the Campagnolo brand is known for.
