Box One 11S Shifter
With improved ergonomics and fast controls, Box One™ Shifters provide smooth and accurate transitions from gear to gear. Up to five shifts on the throw helps ensure you can move up the cassette quickly while climbing. A lightweight, machined clamp and premium, cast aluminum lever help to reduce weight.
