At the heart of any good component group are the shifters. Not only are they responsible for much of the crispness and feel during shifts, but they're the primary point of contact between hands and bars. The Shimano Dura-Ace 9100 STI Lever Set is completely redesigned for improved ergonomics, and now offers additional lever-reach refinement to fit a wide range of hand sizes. Front and rear shift operation is revised, to improve on already outstanding shift performance, and brake feel is also improved through revised internals.  The Shimano Dura-Ace 9100 STI Lever Set is designed to work with Shimano's latest 11 speed 9100 group, and is built to Shimano's most premium standards of quality. The dual control STI levers are sold as a set (left and right levers), with Black hoods and carbon fiber brake levers.
