SRAM XX1 11-Speed Crankset - BB30 QF156

ONE. AND ONLY. SRAM XX1 was built with a dedicated 1X drivetrain philosophy—making it simpler, lighter and more durable than any other. No matter where you ride, no matter what you’re up against: SRAM XX1. UNSTOPPABLE. 

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. 

SIMPLER, LIGHTER AND MORE DURABLE - XX1 CRANK

KING OF THE RING

Developed for maximum chain control, each tooth’s thickness is precisely CNC-machined to support the chain’s inner and outer links perfectly. Six available chain rings (28-30-32-34-36-38) allow you to tune your gear range to match your terrain, wheel size and riding style. Each X-SYNC™ chain ring fits a single, universal spider—allowing you to change rings without removing the light-weight carbon crank arm. Carbon arms with forged aluminum spider. New spider design allows for easier ring changes.
