The Chorus QS Ergopower levers come with composite lever blades identical to Record. The ergonomics of the levers themselves are the same, and the main difference comes in the weight of the internals themselves. Comes standard with a full Campagnolo cable kit. Like Record, Campagnolo incorporates Quick Shift technology in the Chorus levers, allowing shifts to occur with lighter force from your fingers. Ideally you'd purchase these levers along with a Campagnolo Chorus QS front derailleur to optimize shifting quickness and crispness.
