What sets the SRAM Rival Flattop E1 Chain apart from standard chains?

The Rival Flattop E1 chain is built around SRAM's flat-top link design, which allows the chain to run on both 12-speed and 13-speed road and gravel drivetrains — one chain format that covers the current and next generation of SRAM road AXS systems. Cutouts on the outer links shed meaningful weight compared to the previous generation Rival chain, while the Hard Chrome finish adds surface hardness for improved wear resistance and durability over long miles. The result is a chain that is lighter than it was before and tougher than you would expect at this price point.

At 126 links it is appropriate for most road and gravel builds out of the box. Compatible with PowerLock and Flattop connector links for easy installation and removal without a master link tool. This is the chain that ships with Rival AXS groupsets and pairs correctly with the Rival Flattop cassette and Rival XPLR drivetrains. If you are stocking up on chain for a high-mileage training season or a gravel build, the E1 is an honest, durable choice that does not ask for a premium price.
