Campagnolo Chorus 12-speed Carbon Chainset (170 mm 34/50) Size: 170 mm

The new Chorus crankset is a true concentrate of technology and versatility. Technically advanced thanks to unidirectional construction technology in carbon fiber, it is produced directly molded without any surface coating and has an Ultra-Torque steel axle like the Record crankset. It is versatile thanks to its new ring of 123 mm bolts that, while giving it an extreme-performance structure, also ensures a wider variety of use segments. Available with 165, 170, 172.5 and 175 mm cranks, the new smaller ring of bolts on the Chorus crankset makes it compatible with 52/36, 50/34 chainrings and with the brand new 48/32 crowns.
