Description
The XTR M9100 derailleur brings a new level of drivetrain silence thanks to decreased tension in the low gear position and an added bumper on the pulley cage. Larger 13T pulleys increase efficiency and chain management while compatibility with Shimano’s new 12-speed cassettes boosts range.
- SGS/Long Cage is designed for the 51t XTR cassette
- GS/Medium Cage is designed for 45t XTR cassette
