Sram Xx1

SRAM XX1 was developed with a special 1X drivetrain philosophy, making it simpler, lighter, and more durable than any other drivetrain. No matter where you are or what stands in your way: SRAM XX1 is unstoppable.

Purposeful Pursuit
Based on a groundbreaking single-chainring carbon crank and seamlessly integrated components, the SRAM 1X drivetrain offers flawless chain management and faster, more precise shifting. However, the relationship between the XX1 components goes beyond mere compatibility. From the X-HORIZON derailleur with TYPE 2 technology to the 11-speed cassette with an incredibly wide gear range of 10-42 teeth, each component is designed to work perfectly with the others to achieve what no other single-chainring drivetrain has accomplished.

X-HORIZON Derailleur
With its horizontal parallelogram design and offset upper pulley, X-HORIZON technology ensures consistent chain spacing across all 11 gears and delivers fast, precise shifting performance. ROLLER BEARING CLUTCH technology reduces chain slap. CAGE LOCK technology makes wheel changes easier under the high spring tension of the derailleur. Together with the XX1 Trigger or Grip Shifter, the XX1 X-HORIZON derailleur forms the backbone of X-ACTUATION technology for incredibly smooth shifting performance across the entire 10-42 cassette.
