Shimano XTR RD-M9100 SGS 1x12-speed rear derailleur

To ensure efficient gear shifting despite the significant gear ratio difference of the 10-51 cassette, the Shimano XTR M9100 rear derailleur is available in an SGS model with an extra-long cage. The XTR M9100 features the Shadow+ system, which provides a compact derailleur that is less exposed to impact and better chain tension for quieter and more reliable shifting. More rigid, this derailleur offers even more precise and durable shifting. For better performance and to cope with the significant difference in cassette tooth count, the pulleys now have 13 teeth.

In this SGS version (extra-long cage), this derailleur is compatible with Shimano 12-speed single chainring drivetrains fitted with a 10-51 tooth cassette.
