Campagnolo Chorus 12-Speed Left Hydraulic Lever/Rear 140 Caliper

Featuring at a more attractive price point but still offering similar performance benefits to Campagnolo’s higher-end offerings, the Chorus 12-Speed Left Hydraulic Lever/Rear 140 Caliper combination affords accurate gear shifts and powerful braking in all conditions. The hood shape and brake lever are ergonomically designed to improve grip, and the larger gear lever works in tandem with its immediate shifting engagement to grant front derailleur changes with minimal effort.

The flat-mount hydraulic disc brake caliper body promises secure, positive braking and works in unison with the 22mm diameter piston and frictionless brake pad return to ensure excellent control. A metal plate inserted between the piston and the pad cancels braking vibration, and a brake pad wear indicator shows when replacement is needed. This caliper is designed for rear brake use with a 140mm rotor, and has a rider weight limit of 82kg.
