Shimano Deore SL-M4100-IR 10-speed I-Spec EV right-hand MTB shifter with gear indicator

The Shimano Deore M4100 rear derailleur is compatible with 10-speed drivetrains. It is available in a version designed for direct mounting on Shimano I-Spec EV brake levers for seamless integration into your cockpit, adding a premium finish to your mountain bike. It is still possible to adjust the position of the shifter independently of that of the brake lever.

Its ergonomics have been designed to provide quick and intuitive access to the levers, whilst offering the smooth and responsive action that characterises Shimano shifters. The main lever allows you to change up to 3 gears in a single movement to quickly adapt your gearing to the terrain. The Optical Gear Display shows which gear is engaged, allowing you to see how many gears are left on either side.
