Sram Rival AXS D1 X-Sync (Direct Mount)

Secure Control.

Maintain absolute chain security on every road with the Sram Rival D1 Direct Mount Chainring. Designed specifically for Rival 1x12 drivetrains, this chainring features Sram’s legendary X-SYNC technology; the original narrow-wide tooth profile that revolutionized 1x systems. Whether you're grinding out a steep gravel climb or flying down a chunky descent, this direct-mount ring ensures your chain stays exactly where it belongs without the need for a heavy chain guide.

Why the Rival D1 Direct Mount is the Smart Choice:

• X-SYNC™ Narrow-Wide Technology: The tall, square tooth edges engage the chain earlier than traditional triangle-shaped teeth, while the narrow-wide profile manages the chain perfectly to prevent derailment over bumpy terrain.

• Direct Mount Simplicity: The direct-mount interface eliminates the need for a separate spider and chainring bolts. This results in a lighter, stiffer assembly and a much cleaner aesthetic for your Winspace or 3T gravel build.

• Mud-Clearing Design: Engineered with specialized recesses for the inner chain links and rollers, this ring sheds mud and debris effortlessly, maintaining smooth performance even in the worst cyclocross or gravel conditions.

• Long-Lasting Durability: Constructed from high-strength aluminum with a durable black anodized finish, it’s built to withstand thousands of shifts and the high-torque loads of modern 12Speed riding.

• Versatile Gearing Options: Available in a full range of sizes (38T, 40T, 42T, 44T, and 46T), allowing you to tailor your gear inches perfectly to your local terrain.

• Speed: 12Speed

The Alegro Perspective: If you are finding yourself "spinning out" on descents or struggling on the steepest climbs, swapping your chainring is the most effective way to re-tune your bike. Because it uses the 8Bolt direct mount system, it’s also the gateway for upgrading your Rival crankset to a power meter in the future.

Absolute Retention. Minimalist Design. Optimize your gearing.
