SRAM X01 Type 2.1 Rear Derailleur
Couldn't load pickup availability
The SRAM X01 Type 2.1 rear derailleur is a long-cage rear derailleur for MTB with 11 speeds, designed for cassettes up to 42 teeth. The X-HORIZON horizontal parallelogram design maintains the same chain gap across all 11 gears, reduces shifting effort and limits ghost shifting.
ROLLER BEARING CLUTCH technology reduces chain bounce and chain slap, while CAGE LOCK makes wheel fitting and removal easier. Paired with the X01 shifter, it forms the X-ACTUATION system for smooth shifting. The model is available in black or black-red: the choice concerns only the colour, so your bike's style is what matters.
