Campagnolo Guarn. Chorus Ultra-Torque Carbon 12-speed.

The new Chorus crankset is a true concentrate of technology and versatility. It is technically advanced because it uses unidirectional carbon fiber construction technology obtained directly from the mold without any surface painting and uses the Ultra-Torque steel axle like the Record crankset. It is versatile because its new giro 123mm bolts, while giving an extreme performance structure, ensures a wider variety of segments of use. Available in 165, 170, 172.5 and 175mm cranks, the new and reduced bolt giro s of the Chorus crankset make it compatible with 52/36, 50/34 chainrings and the brand new 48/32 chainrings.
