Description

Description

Because of the larger 12-speed cassette in the Sram XX1 Eagle groupset, the X-Horizon rear derailleur design of the Sram XX1 12-speed has been adapted. The cage has been made slightly longer and the lower jockey wheel now has 14 instead of 12 sprockets. The Roller Bearing Clutch has been refined and provides linear force over the entire range of the cage.

Assembly

Loosen and tighten the gear cable.
To loosen and tighten the bolt with which the gear cable is attached to the derailleur, you need a 5 mm Allen key. You can find these here.

Removing the chain.
Before you can remove the derailleur, you will also have to remove the chain. How to do this, you can read here. You need a chain tool for that. We have these here. Make sure you buy one of the right brand and the right number of speed.

Use assembly grease for mounting.
If you are going to mount the new rear derailleur, it is best to apply some mounting paste to the threads of the derailleur hanger. You can buy this aseembly grease here.

Assembling jockey wheels.
To mount jockey wheels you need an Allen key of 2.5mm or 3mm. A handy Allen key can be found here:

User tips

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.

Good product... perhaps a little too delicate for 'normal' users

- Danilo 17 August 2021

As usual SRAM XX1 is a safety. Flawless operation, light, precise... In my opinion, however, the materials are a bit too 'delicate' for XC use with people who can't afford to change components for 'every race'... I had the previous model and in a short time, unfortunately, the clutch came loose making the shifts not precise, the materials were damaged by the stones. It's probably suitable for professional use that has no problem changing components when needed. I have however put my trust in SRAM again in the hope that the new version will be more robust.

Fitted on my Giant Trance as a replacement for the SX I was not satisfied with. Now it is as it should be: trouble-free shifting, finally.

Good but expensive

- Jos 17 October 2020

Nice lightweight derailleur that shifts very well. Perhaps a bit more susceptible to damage due to the carbon cage. The spring seems tighter than of the cheaper eagle variants, making it shift just a little better.
