Campagnolo Chorus 曲柄组 2x12

Campagnolo Chorus 12s Ultra Torque 2x12-speed crankset

The 12-speed chorus crankset is a true concentrate of technology and versatility. It is technically advanced because it uses the construction technology with unidirectional arrangement of the carbon fibers, which is obtained directly from the mold without surface coating, and how the Record crankset uses the Ultra-Torque inner bearing shaft made of steel. It is versatile because its new 123mm bolt circle, while providing a structure of extreme performance, provides a wider variety of application segments. The new, reduced bolt circle of the Chorus crankset makes it compatible with 52 / 36-, 50/34 chainrings and the latest 48/32 crowns.
