The Campagnolo Super Record 12 speed crankset has an improved aerodynamic design. The carbon crankset arms extend to the chainring, creating a stiffer and more aesthetically pleasing design. Super Record hollow carbon construction provides a lower weight without sacrificing stiffness or reliability. The twin BCD chainring bolt design, 4+4 further enhances the crankset stiffness and versatility. Available in four crank length sizes and three chaining combinations. Ultra Torque (UT) bottom bracket system with titanium axle and fixing bolt.
