Shimano XT M8000 Shadow Plus 11 Speed Rear Derailleur

With the Shimano XT RD8000 you can change gears directly and smoothly, this will save you a lot of energy on the trails or single tracks. The M8000 features Shimano's optimized SHADOW RD+ technology with a soft angle and a low profile design. This results in smoother shifting and an improved chain stability. The renewed derailleur wheels with a larger tooth profile ensure a improved performance and effective shifting. The XT M8000 rear derailleur is compatible with direct mount systems and 1 × 11, 2 × 11 or 3 × 11 setup.

Skew derailleur hanger?
A problem that crops up often is a skew derailleur hanger. It can happen if the derailleur knocked into something, for example in the case of a fall on the bike. Luckily it can be fixed! You can read more here.

Clean the jockey wheels well too!
Just like the chain, the jockey wheels on a derailleur get super dirty. As a result the shifting is not as good and it does the lifespan of your derailleur no good. For that reason, it's a good idea to clean the jockey wheels at the same time when you clean and lube your chain. Do this by running a cloth along the jockey wheel while gently turning the chain. Of course it gets to a point where the jockey wheels are worn out. In this blog post you can find out more about when jockey wheels should be replaced and what you'll need.
