Technologies:
Cage Lock™:
With Cage Lock it is easier to install your chain and (de)install your wheel. This is done by pressing the cage forward and fastened with a button.

Roller Bearing Clutch ™:
This technique ensures you drive-chain is maximum stabilized, even during the roughest terrain. With this technique are unwanted derailleur movements and chain slap eliminated without having to compromise on its precision gear changing.

X Actuation ™:
Specially designed for SRAM 1X, X-Actuation ensures changing gears is sharp and consistent across the entire cassette of 10 up to 42 teeth.

X-HORIZON ™:
The X-HORIZON™ rear derailleur ‘straight parallelogram’ design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.

X-SYNC ™:
The 1X chainring delivers the highest performance and assures durability. The SRAM X-SYNC™ long square teeth engage the chain earlier than traditional triangular teeth. The X-SYNC chainrings have a 'mud clearance' recess between the chain links and chain ring, to ensure the mud falls out. The X-SYNC ™ rings are an integral part out of the SRAM 1X ™ powertrain. Designed in Germany.

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.
