SRAM GX1 11-speed Rear Derailleur

The SRAM 11s rear derailleur has all technologies what the SRAM top end derailleurs also have. The GX1 is slightly heavier but much more affordable.

Technologies:
Cage Lock ™:
With Cage Lock it is easier to install your chain and to (dis) assembly your wheel. This is done by pushing the cage forward and fasten it with a button.

Roller Bearing Clutch ™:
This technique ensures your drive is max. stabilized, even during most rugged terrain. With this technique are unwanted movements from your derailleur and your chain stroke eliminated without having to compromise on the precision shifting.

X-Actuation ™:
Specially designed for SRAM 1X, X-Actuation ensures that shifting remains sharp and consistent across the entire cassette of the 10th till the 42 teeth.

X-HORIZON ™:
The rear derailleur with 'straight parallelogram' design ensures that all horizontal movements are eliminated, the shifting is less heavy and it prevents ghost shifting. For fast and precise shifting the top roller has a fixed distance with the cassette.

X-SYNC ™:
The 1X chainring delivers the highest performance and assures durability. The SRAM X-SYNC ™
long square teeth get hold of the chain much quicker than traditional triangular teeth. The X-SYNC gears have a 'mud clearance' recess between the inner chain links and the chain ring that ensures the mud falls out. The X-SYNC ™ chainrings are an integral part of the SRAM 1X™ drivetrain. Designed in Germany.

Assembly

Require a derailleur clamp?

Some bicycles do not have a braze on for the front derailleur. To mount this front derailleur, you can use a derailleur clamp.

Tightening and loosening the gear cable
To loosen and tighten the bolt that attaches the gear cable to the derailleur, you will need a 5 mm Allen key. These can be found here.

Disassembling the chain
Before you can remove the derailleur, you must remove the chain. How to do this you can read here. For this you need a chain rivet tool, which you can find here. Make sure you get the right brand and number of speed.

Use assembly paste to mount
When you mount your new rear derailleur, you should put some assembly paste on the threads of the derailleur pad. You can buy this from here.

Mounting derailleur pulleys
To fit derailleur pulleys you need a 2.5 mm or 3 mm Allen key. A handy Allen key can be found here.

User tips

A crooked derailleur hanger?
A common problem is a warped derailleur hanger. This can be caused by the derailleur coming into contact with something hard, for example during a fall. Fortunately, this can be repaired! Find out more here.

Make sure you clean your derailleur pulleys too!
Like the chain, derailleur pulleys get very dirty. This makes for a less enjoyable ride and doesn't help with the durability of your drivetrain. Therefore, when cleaning the chain and / or oiling the chain, it is advisable to also clean the derailleur pulleys. Do this by gently turning the chain while you run a cloth along the derailleur wheel. However, at some point the derailleur wheels will be worn out.
