Sram Rival AXS D1 X-Sync Road Direct Mount 8Bolt

Sleeker, Lighter, and Rock-Solid Chain Retention.

The Sram X-SYNC Road Direct Mount chainring is the ultimate choice for riders who want to push the boundaries of their 1X drivetrain. By eliminating the traditional spider and bolts, this direct-mount design creates a stiffer, more aerodynamic interface while shaving approximately 25–50g off your crankset. Whether you’re building a dedicated gravel grinder or a crit-focused road machine, this ring provides the cleanest look and most reliable performance on the market.

Performance Highlights:

• X-SYNC™ Narrow-Wide Technology: The tall, square-edged teeth engage the chain earlier than traditional triangle teeth, providing maximum chain control even on the roughest terrain.

• Superior Mud Shedding: Engineered with recessed mud-clearing channels for the inner chain links and rollers, ensuring your drivetrain remains silent and smooth in the worst conditions.

• Laser-Etched Durability: The finish isn't just for looks—the laser-etched surface is designed to resist wear and maintain its high-end appearance over thousands of shifts.

• Streamlined Integration: The 8-bolt direct mount interface provides a direct connection to the crank arm, maximizing power transfer and creating a seamless, modern aesthetic.
