Sram X01

The SRAM X01 drivetrain continues the tradition of SRAM's victorious 1X philosophy - everywhere on the mountain. The tuning is simpler, the drivetrain is lighter, and the shifting is fast and precise. In short: X01 is the right drivetrain for any terrain - anytime. Unstoppable. With its horizontal parallelogram design and offset upper shifting pulley, X-HORIZON technology ensures a consistent chain gap and quick, precise shifting across all 11 gears. The Roller Bearing Clutch technology reduces chain slap. The Cage Lock technology makes wheel changes easier under the high spring tension of the derailleur. Together with the X01 Trigger or Grip Shifter, the X01 X-HORIZON derailleur forms the backbone of X-ACTUATION technology for an incredibly smooth shifting performance across the entire 10-42 cassette.
