Deragliatore Posteriori Shimano XT M8050 Di2 11-speed

The new Shimano XT M8050 front derailleur enables you to shift quickly and accurately with just one shifter. The Deore XT derailleur will quickly respond to your commands, should you find the going gets vertical all of a sudden. A light touch of the Di2 button is all you'll need to change into a more efficient gear. You'll always have the right gearing possibilities to switch between tough climbs, technical descends, or adrenaline-fuelled races. Comes with the adjustable multi-shift or Synchro Shift technology.

The Synchro Shift technology in the shifters allows you to change gears at both the front and the back with just a single shifter. An adjustable shift-range allows you to tune when the Di2 system will automatically shift into the large ring when changing up, or into the small one when changing down. Whichever gear ratio you choose, Shimano's Rhythm Step ensures you'll get it with as little shifts as possible. This ensures you as a rider are able to continue at a more stable cadence and ride more fluently. No major jumps in gears, no overworked muscles or joints, just effortless (relatively) pedaling in your own choosen gear range. No compromises, rather just focus on simplicity and fun!

Loosening and tightening the gear cable
You can find the 5mm Allen key that you need for adjusting the limit screws here.

Removing the chain
Before you can install the new derailleur, you'll need to remove your chain. You can read about how to do that in this blog. You'll need a chain breaker, which you can find here. Some multi-tools contain a chain breaker. Make sure that you select a chain breaker for the right speed chain though - the size of the pins is different according to the speed of the chain.

Always use assembly grease
If you're fitting a new derailleur, you should definitely apply assembly grease on the screw thread of the derailleur pad. You can find our selection of assembly greases here.

Fitting jockey wheels
To fit jockey wheels you need a 2,5mm or 3mm Allen key. Find a handy Allen key set here.

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.
