Shimano Deore M4100 SL-M4100-IR Right Shift Lever 10-Speed I-SPEC EV

Shimano Deore M4100 Shift Lever

The Shimano Deore SL-M4100-IR is a right-hand rear shift lever designed for 10-speed MTB drivetrains. Part of the Deore family, it features RAPIDFIRE PLUS technology for fast and responsive shifting, providing intuitive control when riding on changing terrain.

The SL-M4100-IR also uses the I-SPEC EV mounting system, allowing the shift lever to be integrated into a compatible handlebar cockpit and its position adjusted to suit the rider.

RAPIDFIRE PLUS and 10-Speed Shifting

The RAPIDFIRE PLUS system is designed to provide fast and intuitive shifting. The main lever allows the rider to shift up to 3 gears at once, making it easier to move quickly through the cassette when the riding conditions or gradient change.

The lever is specifically designed for use with 10-speed MTB rear derailleurs.

I-SPEC EV Mounting

The Shimano Deore SL-M4100-IR uses the I-SPEC EV mounting system, developed by Shimano to optimise the positioning and integration of controls on the handlebar.

The lever provides a 14 mm slide adjustment range, allowing its position to be fine-tuned according to the rider's preferences and cockpit setup.

2-WAY RELEASE and Multiple Shifting

The 2-WAY RELEASE function allows the release shift to be operated either by pulling the lever with the index finger or pushing it with the thumb. This provides greater flexibility in how the control is operated while riding.

The main lever also allows the rider to shift up to 3 gears at once, making larger gear changes quicker and more convenient.

OPTICAL GEAR DISPLAY

The lever is equipped with an OPTICAL GEAR DISPLAY, allowing the selected gear to be viewed directly from the shift lever.

A practical feature that provides an immediate reference to the current gear while riding.

Lever Adjustment

In addition to the 14 mm slide adjustment range, the shift lever features cable adjustment. This allows the control position to be fine-tuned according to the rider's preferences and setup.

10-Speed MTB Rear Derailleur Compatibility

The Shimano Deore SL-M4100-IR is specified by Shimano for use with 10-speed MTB rear derailleurs. Before purchasing, check that your drivetrain is compatible and, in particular, that your brake lever or cockpit setup supports the I-SPEC EV mounting system.
