SRAM X01 Type 2.1 11-Speed Rear Derailleur
- 11-speed specific
- Carbon body/cage, aluminium hardware
- 12-tooth X-SYNC pulley wheels
The updated SRAM X01 rear derailleur is nearly identical in function, weight, and performance to the original, with SRAM making some small improvements to the derailleurs clutch mechanism and bearings to improve overall performance and longevity.
Thanks to its “horizontal parallelogram” design, X-Horizon can keep the chain gap the same across all 11 gears. By taking vertical movement out of the equation, this design doesn’t just make shifting faster-it reduces shift force and eliminates ghost shifting. Roller Bearing Clutch technology reduces bounce and chain slap, while Cage Lock technology makes wheel removal and installation easier than ever before.
Paired with the X01 shifter, the X-Horizon rear derailleur forms the backbone of X-Actuation technology: the key to totally smooth shifting action.
