Shimano's Deore XT Dyna-Sys Rapidfire Shifters live up to the XT tradition. The ergonomic shift levers feature light, crisp action that leads to sharp, definitive shifts. Two-Way Release and Multi-Release ensures you have the control grab gears anyway you like. With the mode-convertible front shifter you can set up the 2x or 3x drivetrain of your dreams using the same shifter set. A removable Optical Gear display offers heads-up monitoring of gear choices, and I-Spec compatibility streamlines your handlebar setup.
