SRAM X01 Type 2.1 Rear Derailleur

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.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
