XTR M9100 12-Speed Rear Derailleur

The XTR M9100 series of derailleurs brings a new level of drivetrain silence thank 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.

Like a fine wine, some things are worth waiting for and the new Shimano XTR M9100 12-Speed Rear Derailleur has certainly been worth the wait. Proven Shadow RD+ technology keeps the mech out of harm's way while delivering shifts so smooth, you'll need a jazz soundtrack to accompany your riding. The cold forged aluminium body is both supremely light and incredibly hard wearing - this is not delicate 'one race' bit of kit. A carbon front plate and alloy back make the Shimano XTR M9100 12-Speed Rear Derailleur' cage light, stiff and durable. The new 10 tooth upper jockey wheel reduces noise, with a rubber anti-chain buzz cushion making the mech quieter still. Meanwhile the big 13 tooth lower jockey wheel, with fully sealed bearings, makes the jump from 10 all the way up to 51 teeth completely trouble free. To experience the shifting that you have been waiting for, the Shimano XTR M9100 12-Speed Rear Derailleur is the only 12 speed mech your bike will ever need.
