Description
The Shimano Dura Ace 9100 11-speed rear derailleur has been completely redesigned compared to its predecessor. Several key elements from the mountain bike range have been used, such as the Shadow Technology. Shadow refers to the derailleur now being completely below the cassette, making it harder to get damaged by external factors. The capacity has also increased to 35T, allowing you to run up to a 11-30 cassette.
• Low profile design
• Total capacity: 35T
• Weight: 158g
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.
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.
