What makes the SRAM Force Flattop E1 Chain the right choice for AXS builds?

The SRAM Force Flattop E1 chain is the standard-bearer for SRAM's road and gravel AXS chain platform, combining the Flattop outer plate geometry with the durability and weight balance expected at the Force tier. The flat outer plate profile reduces friction at the chainring and cassette interface compared to traditional chain profiles, which translates to quieter running, reduced drivetrain wear, and smoother engagement across all 12 sprockets on road or all 13 sprockets on XPLR gravel. This single chain covers both platforms, making it the correct spec whether you're running a Force AXS road groupset or a Force XPLR 13-speed gravel drivetrain. At 126 links it ships ready to run on most standard builds.

The PowerLock connector is included for tool-free installation and removal, and the chain is compatible across SRAM RED AXS and Force AXS components within the same speed platform. Replace at 0.5% stretch to maximize the service life of your cassette and chainring — swapping chains proactively is always cheaper than replacing worn cassette teeth. For riders who want the correct Force-spec chain with dual-platform compatibility and long service life, the Flattop E1 is exactly what belongs in your drivetrain.
