Product technical specifications

TECHNOLOGIES

X-HORIZON - The parallelogram design of this rear derailleur limits movement along the horizontal axis, eliminating so-called " ghost shifting" and reducing shifting force at the same time. The large offset of the upper shifting roller ensures a constant chain distance in every gear for faster and more precise shifting.

X-ACTUATION - X-ACTUATION technology, specially developed for SRAM 1X, ensures precise and constant shifting along the entire cassette with 10-42 teeth.

X-SYNC - A CNC-machined pattern with alternating wide and narrow tooth spacing is repeated around the entire XX1 chainring, perfectly mimicking the inner and outer links of the 1X11-speed XX1 chain for optimal control.

CAGE LOCK - Due to the Cage Lock Technology in the rear derailleur, removing and fitting the rear wheel and chain is quicker and easier than ever before. Simply push the cage forward (to release the chain tension) and lock it.

ROLLER BEARING CLUTCH - In the new X0 and X9 series rear derailleurs, Roller Bearing Clutch Technology ensures that the cage can build tension. A needle bearing prevents any light forward movements, the chain remains under tension and does not hit the strut. This prevents the chain from jumping off even without a chain guide on the crankset.
