Product Description
SRAM XX1 - Unique
SRAM XX1 was developed with a special 1X drive philosophy and is therefore simpler, lighter and more robust than any other drive. No matter where you're going or what's in your way: SRAM XX1 is unstoppable.


Cage Lock

Thanks to the Cage Lock technology in the rear derailleur, rear wheel removal and installation are faster and easier than ever. Simply push the cage forward (to release the chain tension) and lock.

Roller Bearing Clutch
Roller Bearing Clutch gears provide maximum drive stability - even on murderous and highly demanding terrain. Roller Bearing Clutch technology puts an end to shaky rear derailleurs and beating chains without sacrificing precision.

The X-Actuation technology specially developed for SRAM 1X ensures precise and constant shifting operations along the entire 10-42 tooth cassette.The parallelogram design of the X-Horizon rear derailleur limits movement along the horizontal axis, eliminating ghost-shifting and reducing shifting force. For faster and more precise shifting, the large offset of the upper pulley ensures a constant chain distance in each gear.


X-Sync 1X chainrings from SRAM ensure maximum performance and durability. The long SRAM X-Sync tooth edges grip the chain earlier than traditional triangular teeth. The sharp and narrow tooth profile as well as the rounded inclined edges support the chain guide. To provide the best possible performance even on muddy terrain, the X-X-Sync chainrings have recesses for removing dirt and mud from the inner chain links and rollers. The X-Sync chainrings manufactured in Germany are an important part of the 1X drive from SRAM.
