SRAM GX 11-speed Rear Derailleur

The SRAM GX 11s rear derailleur features many technologies that are also equiped on the flagships from SRAM. The GX rear derailleur is slightly heavier but much more affordable. The derailleur is for a 2 x 11 speed cassette of 10 up to 42 teeth. That gives you the biggest ever range with a shifter group. No climb is too steep and you will not lose maximum speed when you can go full throttle.

Mounting derailleur pulleys

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.
