The SRAM Red E1 X-Sync Threaded Mount Chainring is built specifically for use with the SRAM RED XPLR AXS power meter, integrating a Thread Mount spider design that sheds weight and improves drivetrain stiffness compared to a traditional bolt-circle setup. The result is a more direct connection between crank and chain — one that holds precise chainline through hard efforts and long days in the saddle. X-Sync tooth profiling works in tandem with SRAM's Flattop chain to keep engagement clean under load, whether you're pushing a bigger gear on the flat or spinning a compact ring over mixed terrain. Ring swaps are straightforward, though you'll need the SRAM Thread Mount Chainring Removal Tool to do it properly. Five tooth counts — 38t through 46t — give you genuine flexibility to match gearing to your riding without changing the rest of the drivetrain.
