ONE. AND ONLY.
SRAM 1x™ is the only one you need: less weight, better chain control and the ability to sync up with any riding style. Our 1x drivetrain philosophy focuses on optimizing how components work together—crank to ring, tooth to chain, shifter to derailleur, derailleur to cassette, and cassette to wheel. No matter where you ride, no matter what you’re up against, SRAM 1x takes you further.
