Mountain bike rear derailleur Xx1 Type 2.1 11 Speed

THE ONE AND ONLY. SRAM XX1 was designed with a dedicated 1X drivetrain philosophy: to be simpler, lighter and more durable than all the others. Wherever you go, whatever you do: SRAM XX1 IS IMPERATIVE.

MAXIMUM IMPACT

With its "horizontal parallelogram" design and signature roller spacing, X-HORIZON™ keeps chain blur constant throughout the 11 gears, delivering fast, precise shifts. By limiting all movement to the horizontal axis, this design provides more speed, reduces shifting force and eliminates unintended shifting problems. ROLLER BEARING CLUTCH™ technology reduces rebound and prevents the chain from banging too often. CAGE LOCK™ technology makes it easier than ever to remove and install wheels. Combined with the XX1 shifter, the X-HORIZON rear derailleur is the centerpiece of X-ACTUATION™ technology for incredibly smooth shifting.
