Why We Like The XT RD-M8000 Rear Derailleur

Bringing constant refinement to the 11-speed XT drivetrain, the Shimano XT RD-M8000 Rear Derailleur offers improved chain retention when you're riding across jarring, rock-strewn trails. Benefiting from trickle-down technology from the XTR group, This XT Deore derailleur utilizes Shadow RD+ technology keeps the chain from bouncing around with its handy stabilizer switch. The Shadow design is optimized for increased stability with its slanted position, allowing for silky-smooth shifting in every gear.

The XT's robust aluminum construction takes a serious beating without fuss, equating to worry-free confidence when you're rallying across technical terrain. In conjunction with a low-friction shift cable, Shimano claims shifting requires 20% less effort. Other key features include an easy-to-adjust chain stabilizer for effortless fine-tuning, as well as Direct Mount attachment with compatible frames for a stronger and lighter mount interface. As a bonus for riders with older frames not compatible with Direct Mount, the included link attaches in a conventional manner.

Using it with goat link, 11'34

I've used it several times
5' 8"

I'm an older road racer and always looking to be fast and still be able to climb. On a race bike 53'39 front and now 11'34 rear. With the goat link, I haven't lost any speed and gained in climbing. Perfect! Using medium cage and can grow it to 11'40. All Shimano.
