SRAM XX1 Eagle DUB Boost crankset for maximum race power
The XX1 Eagle DUB Boost crankset takes your mountain bike to race level. Ultralight carbon arms, a stiff DUB axle, and a precise X-SYNC 2 direct-mount chainring deliver explosive power and full control on every line.
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. Thanks to the Boost chainline, it fits perfectly into modern MTB frames with wide hubs and fat tires. The DUB technology combines a particularly durable axle with easy bottom bracket compatibility. You get a drivetrain that is uncomplicated to build and can withstand even the toughest competition.
Direct drive with 1x12 Eagle
With the 1x12 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. The special tooth profile keeps your chain securely on the chainring, even on rocky downhills and rough high-speed sections. You can fully concentrate on your line while your drivetrain operates quietly, efficiently, and reliably.
For performance-conscious mechanics
The crankset comes in practical bulk packaging, ideal for mechanics who want to avoid unnecessary packaging. With a 170 mm crank arm length, it's particularly appealing to aggressive riders who appreciate more ground clearance on technical sections. Combined with a compatible DUB bottom bracket, your high-end drivetrain is installed in no time and ready for the next race day.
