The Shimano XT M8100 12 speed rear derailleur is relatively lightweight, is durable and shifts very smoothly. It incorporates the same technology as the XTR rear derailleur, but this XT derailleur is priced at much better price point!
Shifting is extremely easy with the Shimano XT M8100, because Shimano has developed new shifting technology. This so-called Shimano Hyperglide+ technology will make shifting even smoother, even in extreme circumstances or when your pedals are under a lot of pressure. To add to this, Shimano aims for durability and performance with the XT M8100 groupset, as shown by the materials used. While the XTR M9100 rear derailleur features carbon and other lightweight materials, the XT M8100 contains a higher amount of steel and aluminium. This increases durability and decreases the price tag. The only drawback is that the XT type is heavier than the XTR type, but few people will really notice this difference.
In short, if you're looking for a 12 speed rear derailleur with excellent performance, low weight, and great durability, then this Shimano XT M8100 rear derailleur is for you. It features the same technology as an XTR rear derailleur, but will last a lot longer due to the durable materials. You'll have a lot of nice forest rides ahead of you with this derailleur!

Make sure to clean your jockey wheels well!
Just like the chain, the jockey wheels on a derailleur get super dirty. All that dirt makes cycling harder and doesn't do the lifespan of your drivetrain any good. That's why it's important to clean your jockey wheels when you're cleaning or oiling your chain. You can clean them by holding a clean cloth up against the jockey wheels while calmly turning your bike chain. But your jockey wheels will eventually wear out, even if you maintain them properly. In this blog post you can find out more about when jockey wheels should be replaced and what you'll need.

Top quality mtb gear
- Jean-François 23 April 2025
One of the best mtb derailleurs available. Easy to install, it is very reliable with fast and smooth shifting once adjusted (unlike sram shifters which need regular adjustments). Not crazy expensive either
