Light. Stiff. Uncompromisingly fast.

This XX1 Eagle DUB Boost crankset is built for racers and ambitious trail riders. The carbon-tuned design ensures extremely low weight with maximum stiffness, so every pedal stroke is directly translated into forward motion.

You get a drivetrain that is uncomplicated to build and can withstand even the toughest competition.

Direct drive with 1×12 Eagle

With the 1×12 Eagle drivetrain and the 32-tooth X-SYNC 2 direct-mount chainring, you enjoy a huge gear range with a simple setup without a front derailleur.

You can fully concentrate on your line while your drivetrain operates quietly, efficiently, and reliably.
