Get in sync.

It’s no surprise that with the launch of its ground-breaking one-by 12-speed Eagle drivetrain, SRAM also introduces a reworking of its X-Sync chainrings. Building on the original X-Sync's renowned chain retention ability, the X-Sync 12-Speed Direct Mount Chainring changes things up with claims of even better chain control. As with the original design, each tooth is CNC-machined to support the chain's inner- and outer-link widths by providing a variable thickness from tooth-to-tooth, so the chain and chainring essentially lock together as you pedal and push away mud with ease.

The departure in design lies in the tooth shape. Where the original X-Sync teeth took on a boxy shape, X-Sync 2 is narrower to accommodate the 12-speed Eagle chain and features teeth that more closely resemble those of a shark. Boasting aggressive profiling, these teeth hold the chain securely in place like a megaton aquatic predator latching onto a precisely thrown oxygen tank, then let it to glide seamlessly back to the cassette for smooth, friction-free turns.

The beauty of this new profile isn't just in its chain retention ability. It mimics the wear profile seen in the original X-Sync teeth for increased durability and features specific edge shaping to prevent chain suck over time. The direct mount interface also makes swapping out rings a breeze, giving quick flexibility to adapt to different shapes of terrain.

  • Curve setting componentry integrates with the 12-speed Eagle drivetrain
  • 6mm offset for ideal chainline with standard hubs
  • Updated tooth profile provides confident chain retention
  • Direct mount interface makes changing rings a breeze

  • Familiarity: I've put it through the wringer

The new X-Sync ring has been improved over the original and it shows. I used this on an XX1 11speed and it performs perfectly.

will this chainring fits on my old XX1 BB30 crankset?

Hey Javier, yes this will have the same Sram direct mount pattern and as long as you had a direct mount, it will be compatible with your XX1 BB30 crankset. Let me know if you have any other questions and I'd be happy to help - feel free to reach me at 801.204.4547 or cojohnson@backcountry.com. Cheers, Connor

Will this ring mount to an XX1 11-speed crankset? Seems like it should but I wanted to confirm. Thanks.

Hey Peter,

Correct, you can mount this chainring on a XX1 GXP crankset! Feel free to reach out directly if you have any other questions about it and I'd be happy to help!
