Power transfer happens at the crankset, and SRAM's Red AXS E1 DUB 12-Speed Crankset represents their flagship approach to that interface. The one-piece carbon construction eliminates the bonded spider found in previous designs, removing a potential flex point between your effort and the chainrings. SRAM machines the carbon arms using their Exogram hollow construction process, which maintains stiffness while reducing rotating mass where it matters most.

The E1 designation indicates this is SRAM's current Red crankset platform, designed around their 12-speed AXS ecosystem. Direct Mount chainring attachment puts the rings as close to the spider as possible, improving chainline and shifting precision. The rings themselves use SRAM's X-Range tooth profiles, which work with the wider-range cassettes that modern road and gravel setups demand. If you're running a 10-36 or similar cassette, the shifting ramps and pins are optimized for those bigger jumps between gears.

DUB spindle interface means this crankset works with SRAM's unified bottom bracket system. Whether your frame uses BSA threading, PF30, BB30, or T47, there's a DUB bottom bracket that fits. The 30mm spindle diameter provides the stiffness of oversized designs without proprietary headaches. Bottom bracket bearings sit outboard for easy service access, and the whole system uses a self-extracting preload adjuster that simplifies installation and removal.... Read More
