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

The Shimano XTR M9100 GS rear derailleur retains the Japanese brand's DNA with the Shadow+ system still in place, for a compact derailleur that is less exposed to impact and better chain tension to ensure quieter and more reliable transmission.

This derailleur is more rigid, offering even more precise and durable gear shifting. For better performance and to cope with the significant difference in cassette tooth count, the pulleys now have 13 teeth.

In this GS version (medium cage), this derailleur is compatible with Shimano 12-speed single chainring drivetrains only with 10-45 cassettes.
