Product ID: RDM8000GS

The M8000 XT Shadow+ in this GS medium cage version is the perfect 11-speed rear derailleur from Shimano to help you power through the trails with confidence.

For added protection from hazards on the trail, the derailleur has a low profile design. This enables it to continue to deliver reliable and precise 11-speed shifting right across the cassette. The direct mount compatible hanger achieves a simple look while enabling quick and easy wheel changes, and the shadow plus stabilising technology helps reduce chain slap when riding over rough terrain.

Shimano M8000 XT 11-Speed Shadow+ GS Rear Derailleur

With the reliability you'd expect from Shimano, this M8000 XT 11-Speed Shadow+ GS Rear Derailleur is a fantastic addition to your mountain bike build.

Shifting is crisp, accurate and reliable right across the 11 gears available, thanks to a number of innovative design features. The highly rigid outer plates provide an assured and strong bridge for the jockey wheels, with sealed cartridge bearings for prolonged reliability. Meanwhile, four fluorine-coated link pin bushings make this one of the slickest shifting derailleurs on the trails.

Compatible with direct mount rear derailleur hangers, this provides more space around the dropouts for easier wheel removal, as well as allowing for a frame design with shorter chainstays and increased axle sizes.

This 11-speed rear derailleur is compatible with one-by and double chainsets, and the GS cage can accommodate a series of large sprocket sizes on the cassette; 42T (2x11-speed), 46T (1x11-speed), both of which have a high-end limit of 11T.
