SRAM XX1 Type 2.1 11 Speed Rear Derailleur

SRAM XX1 Type 2.1 11sp Rear Mech

With its "horizontal parallelogram" design and pulley offset, the SRAM XX1 (X-HORIZON) 11 speed rear derailleur keeps the chain gap constant across all 11 gears, providing fast, precise shifts.

By limiting all movement to the horizontal axis, this design is faster, reduces shift force and eliminates ghost shifting. By eliminating unwanted chain movement, X-Horizon shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with Cage Lock technology, wheel removal and installation are easier than ever.

Cage Lock With Cage Lock technology in the rear derailleur, wheel removal and installation, as well as chain installation, becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place. Roller Bearing Clutch Features Roller Bearing Clutch (RBC) rear derailleurs deliver maximum drivetrain stability-even through the most punishing terrain.

With RBC technology, derailleur bounce and chain slap are eliminated without sacrificing precision. X-Actuation Developed specifically for SRAM 1X, X-Actuation keeps shifting sharp and consistent across the entire 10 to 42-tooth cassette. X-Horizon The X-Horizon rear derailleur's '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 SRAM X-Sync 1X chain rings provide the highest level of performance and durability. The SRAM X-Sync tall square teeth edges engage the chain earlier than traditional triangle shaped teeth.

The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync rings are an integral part of the SRAM 1X drivetrain.

Large upper pulley offset automatically adjusts chain gap. X-Horizon design reduces shift force and ghost shifting. 12-tooth X-Sync pulley wheels.
