SRAM XX1 Type 2.1 11-speed rear derailleur

SRAM XX1 Type 2.1 11-speed rear derailleur

SRAM rear derailleur for 11-speed systems.

manufacturer number - 00.7518.061.000 Maintains a constant distance of the derailleur from the cassette across all 11 speeds thanks to a horizontal parallelogram and a pulley offset, ensuring fast and precise shifting. By restricting all movement to the horizontal axis, this design is faster, reduces the force needed to shift and eliminates chain skipping. ROLLER BEARING CLUTCH technology reduces derailleur swing and chain slap. With CAGE LOCK technology, removing the wheel is easier than ever. Together with the XX1 shifter it forms the backbone of X-ACTUATION technology for incredibly smooth shifting. - Large upper pulley offset automatically sets the chain distance from the cassette - Horizontal-movement parallelogram reduces the force needed to shift and improves drivetrain performance - X-SYNC pulleys with 12-tooth profile - Type 2 technology: ROLLER BEARING CLUTCH and CAGE LOCK - New quiet pulley tooth design - Weight: approx. 220g
