Campagnolo Chorus 12s Disc Hydraulic Shifter Set

The Campagnolo Chorus 12s Disc Hydraulic Shifter Set brings Italian ergonomics and hydraulic braking precision to riders who want a groupset that performs under pressure without compromise. The carbon lever bodies are shaped to Campagnolo's long-established hand ergonomics — reach is adjustable to fit a range of hand sizes, and the lever action is tuned to feel deliberate rather than accidental.

Shifting is governed by Campagnolo's one-lever, one-action system, which separates shift inputs cleanly so unintended gear changes don't happen when you're deep in a sprint or navigating a technical descent. When you do want to move through the cassette quickly, the system supports up to three sprockets up or five down in a single movement. On the braking side, the hydraulic caliper uses a magnetic pad-return mechanism to eliminate residual drag when the lever is released, and a metal plate between the pad and caliper piston helps cushion vibrations during hard stops. Available individually as left or right levers, with rotor size variants for 140mm or 160mm setups.
