SRAM Rival AXS E1 Flattop Chain

The SRAM Rival AXS Flattop Chain E1 takes SRAM's proven Rival chain platform and refines it for riders who demand both performance and longevity without unnecessary weight. Cutouts on the outer link plates shed grams where they can be spared, while the Hard Chrome finish adds exceptional durability where it matters most—delivering a chain that is ready to go the distance through thousands of demanding kilometres.

At the heart of the Flattop Chain's performance advantage is SRAM's proprietary Flattop technology, which enables a narrower chain profile that not only unlocks X-Range gearing capability but also results in quieter drivetrain operation and increased chain strength and durability over conventional chain designs. Compatible with 12-speed road and 13-speed XPLR AXS groupsets, the Rival Flattop Chain integrates seamlessly into SRAM's AXS ecosystem for precise, reliable shifting in any conditions.

The Hard Chrome finish applied to the inner link plates and rollers delivers four times the elongation and wear resistance compared to standard chain finishes, dramatically extending service life without compromising push pin or ultimate strength. This advanced finishing process means fewer chain replacements, lower long-term drivetrain costs, and consistent shifting performance across the full life of the chain.

Installation is straightforward thanks to the included Flattop PowerLock connector—SRAM's tool-free, precision-engineered connection system that delivers a sure, consistent link every time. Designed to the especially tight tolerances of modern high-speed drivetrains, each PowerLock is engineered for single-use application to ensure maximum security and reliability.

Compatible with 12-speed road and 13-speed XPLR AXS groupsets. Includes Flattop PowerLock connector.
