Mono crankset 12 Speed SRAM RED 1 DUB DM

The heart of the transmission, the 12V SRAM Red 1 DUB DM Mono 46 crankset crankset is designed for demanding cyclists in search of the best-performing equipment. 

Like the double-decker version, it features hollow carbon cranks for greater lightness and an oversized aluminum axle for improved rigidity. It uses a 4-spoke star geometry, 2 of which are lightened with openings to further reduce crankset weight. 

Combined with an X-range cassette starting with a 10-tooth sprocket, the crankset guarantees a wide development range, while offering the aerodynamics and simplicity of a mono drivetrain. However, the most frequently used sprockets feature progressive gearing (only 1 tooth). 

This versatility makes it equally at home on road bikes, cyclo-cross bikes, gravel bikes and touring bikes. And should you wish to install a double chainring drivetrain at a later date, the Mono crankset can be converted using the same cranks.

The SRAM Red 1 is used with the Sram Dub bottom bracket. This standard has the advantage of fitting almost any frame thanks to its universal system, so you don't have to change crankset and bike at the same time. 

On this DM version, the chainring is attached directly to the frame via Direct Mount, which is more reliable, offers greater precision and preserves the aesthetic appearance of the frame.
