Shimano XTR SL-M9100 left-hand MTB lever with double chainring clamp

The Shimano XTR M9100 left shifter is a first for the Japanese brand, which has redesigned the entire control system to offer a simplified system that is as ergonomic and efficient as ever. The shifter now features a single lever to shift between the large and small chainrings. Thanks to its universal clamp mounting system, this control can be mounted on any handlebar, regardless of the brakes used.
