Campagnolo Chorus UT Carbon 2x12v crankset

The Chorus crankset is a true concentration 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 pin like the Record crankset.

It is versatile because its new 123mm bolt circle, while providing a structure with extreme performance, ensures a wider variety of segments of use.

Available with 165, 170, 172.5 and 175 mm cranks, the new and reduced bolt circle of the Chorus crankset makes it compatible with 52/36, 50/34 chainrings and with the brand new 48/32 chainrings.
