SRAM RED AXS DUB Mono 12-Speed Crankset

At the very heart of the drivetrain, the SRAM Red AXS DUB 12-speed single-ring 46-tooth chainset is designed for demanding cyclists seeking the highest-performance equipment. 

Like the double-chainring version, it has hollow carbon cranks for reduced weight and an oversized aluminium spindle for greater stiffness. Its four-arm spider design also makes changing the chainring quick and easy with just one tool.

Paired with an X-Range cassette starting with a 10-tooth sprocket, the chainset provides a wide gear range while retaining the aerodynamics and simplicity of a single-ring drivetrain. The most-used sprockets still have close, progressive steps of just one tooth. 

This versatility makes it suitable for road, cyclo-cross, gravel and touring bikes alike. If you later want to fit a double-chainring drivetrain, the single-ring chainset can be converted using the same cranks.

The Red AXS uses a SRAM DUB bottom bracket. Thanks to its universal system, this standard fits almost any frame, so you won't have to replace your chainset when you change bikes.
