Shimano XTR RD-M9120 SGS 12-speed MTB rear derailleur

The Shimano XTR M9120 SGS rear derailleur retains the Japanese brand’s DNA with the ever-present Shadow+ system. This model is even more compact and robust than the 9100 version, as it has been designed for enduro. Chain tension is also increased to prevent chain skipping and derailment.

Stiffer, this derailleur offers even more precise and durable gear changes. For better performance and to cope with the significant tooth spacing on the cassette, the pulleys now cover 13 teeth.

In this SGS version (extra-long cage), this derailleur is compatible with Shimano 12-speed single-chainring drivetrains designed for enduro, featuring more robust components.
