Campagnolo Chorus 12 Ultra Torque Carbon Crankset Black 170 mm / 50/34t 170 mm Black

New 12x Chorus Ultra-Torque chainset for use with the disc or rim brake groupset. The new Chorus chainset is a true concentrate of technology and versatility. Technically advanced thanks to unidirectional construction technology in carbon fibre, it is directly moulded without any surface coating and has an Ultra-Torque steel axle like the Record chainset. The new 12x cranks are more versatile thanks to the new bolt pcd of 123mm, giving it an extremely solid structure, also ensuring a wider variety of uses. The new smaller bolt circle on the Chorus chainset makes it compatible with 36/52, 34/50 and the brand new 32/48 ratio chainrings. Available in 170mm, 172.5mm and 175mm crank lengths.
