About this item

  • Wide-tooth, narrow-tooth pulley wheel maximizes chain control by fitting inner and outer chain links perfectly
  • X-Horizon design maintains constant chain gap across all gears and eliminates ghost shifting
  • Roller bearing clutch eliminates derailleur bounce and chain slap
  • Cage Lock feature simplifies wheel removal and chain installation
  • Must be used with SRAM 1x11 shifter and cassette


SRAM is one of the largest bicycle component manufacturers who are known for producing quality components and, over the last decade, the brand has pursued an aggressive approach to drivetrain innovation. The XX1 2. 1 is the latest example of SRAM's innovation, and the lastest iteration of SRAM's XX1 X-Horizon Derailleur. The design is based on a horizontal parallelogram that moves the body on a horizontal plane rather than up and down. By limiting the movement of the derailleur, ghost shifting becomes a non-issue. Additionally, there is a small offset between the upper and lower pulleys. No, they aren't misaligned; they are designed specifically to provide a constant chain gap throughout every one of the rear gear ratios. This means smooth, consistent shifting whether you are shifting up or down. The body is fabricated from carbon fiber to maximize strength to weight.

The SRAM XX1 2.1 worked fine. I replaced the XX1 original part with this one. The old model had at least 2 manufactures defects that SRAM would not admit but were different on the XX1 2.1. The spring was stronger and the hanger bolt was an Allen versus a Torques 25. The original model spring kept the unit from shifting realiably and the torques 25 made it impossible to free the hanger from the unit. I am very disappointed that SRAM would not make this right since it was a manufactures defect.

XX1 is the best, no substitute. It's very sturdy and light.

There really is nothing like a new SUPERFAST rear Der. Shifts like a champ and I love the new design of the pullys and the install was very straight forward. I do wish SRAM had included actual REAL directions with it though. Make sure you go online for directions.
