SRAM XX1 Type 2.1 11 Spd Rear Derailleur Rear Derailleurs

Product Description

By limiting all movement to the horizontal axis, this design is faster, reduces shift force & eliminates ghost shifting. By eliminating unwanted chain movement, X-Horizon shifts faster, puts an end to ghost shifting & reduces shift force & chain slap. & with Cage Lock technology, wheel removal & installation are easier than ever. Cage Lock With Cage Lock technology in the rear derailleur, wheel removal & installation, as well as chain installation, becomes faster & simpler. Just pushing the cage forward to create slack & 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 & chain slap are eliminated without sacrificing precision. X-Actuation Developed specifically for SRAM 1X, X-Actuation keeps shifting sharp & 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 & durability. The SRAM X-Sync tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp & 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 & rollers. Engineered in Germany, X-Sync rings are an integral part of the SRAM 1X drivetrain.
