SRAM XX1
Single Minded Pursuit
Driven by a cutting-edge, single-ring carbon crank and seamless component integration, SRAM 1X drivetrain delivers flawless chain management and faster, more precise shifting. But the relationship between XX1 components goes far beyond fitment. From the X-HORIZON™ rear derailleur with TYPE 2 technology to the super wide range 11-speed 10-42T cassette, each component is designed to function synergistically with the others, achieving what no other 1X drivetrain has before.
