The XT groupset is SHIMANO's flagship in the MTB sector. This claim is naturally reflected in the DEORE XT RD-M8100 rear derailleur. It combines pretty much all the rear derailleur technology that Shimano has to offer. This has a clear effect on the extraordinarily high performance of this rear derailleur. You can feel it on the trail! And you can already see it.

It is designed for use on MTBs with 1x12-speed drivetrains and the 10-51T cassette and thus offers a huge gear range. It is characterised by lightning-fast and absolutely precise shifting processes. A 13-tooth idler pulley and a damper counteract drive noise on the one hand and provide a good portion of comfort on the other. The SHADOW RD PLUS technology keeps the chain tension high even in rough terrain.

Both body and cage are made of aluminium. This gives the rear derailleur a weight of only around 284g. The flat design creates safety on narrow trails and also makes a very noble impression.

Furthermore, it is equipped with fluorine-coated pivot bushings. The rear derailleur rollers run on sealed industrial bearings. This guarantees a long life expectancy.

  • MTB optimised
  • Only 1x12-speed with 10-51T cassette

A stabiliser in the rear derailleur effectively prevents the chain from slamming off-road. This improves chain guidance and reduces the risk of the chain jumping off. In addition, the technology ensures less noise in the drive.

Note: should you have any questions regarding compatibility or availability, do not hesitate to contact our customer service.
