SRAM RED AXS DUB Mono 12-Speed Crankset

The true heart of the drivetrain, the SRAM Red AXS Dub Mono 46 12-speed crankset is intended for demanding cyclists seeking the most high-performance equipment. 

Just like the double chainring version, it features hollow carbon cranks for greater lightness and an oversized aluminium spindle providing improved rigidity. It uses a 4-arm spider geometry, allowing, if needed, a quick and simple chainring change using one single tool.

Combined with an X-Range cassette starting with a 10-tooth sprocket, the crankset guarantees a wide gear range, while offering the aerodynamics and simplicity of a single-chainring drivetrain. Nevertheless, a progressive stepping (only 1 tooth) can be found on the most frequently used sprockets. 

This versatility allows it to be fitted to road bikes as well as cyclo-cross, gravel or touring bikes. And if you wish to install a double chainring drivetrain later on, note that the Mono crankset can be converted using the same cranks.

The Red AXS is used with the Sram Dub bottom bracket. This standard has the advantage of fitting virtually all frames thanks to its universal system, saving you from having to change your crankset at the same time as your bike.
