XX1 Eagle DUB 8-Bolt Crank Arm Assembly

True competitors are always looking for a performance advantage — a relentless pursuit of equipment that is lighter, stiffer, stronger and more durable. To create the best drivetrain possible, SRAM re-examined and re-engineered their crankset design. The all-new XX1 Eagle Carbon Tuned crankset is their lightest, stiffest and strongest to date. DUB technology enhances this by simplifying the relationship of the spindle to the bottom bracket and redefining the measure of durability. DUB-powered cranksets mean simplicity, compatibility and durability.

Carbon Tuned

Strength and stiffness where you need it, lightweight like you want it. Carbon Tuned proprietary SRAM carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced carbon architecture ensures the greatest weight savings without compromising strength.

Durability

The relationship between bottom bracket spindle and bearing is the core of DUB technology. It's where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler and better, integrating the relationship between chainring, crank, spindle and bottom bracket. It's this clear system approach that equals better drivetrain performance.
