SRAM | Quarq XX1 Eagle DUB Carbon Crank - black

SRAM | Quarq XX1 Eagle DUB Carbon Crank - black

Real competition guys are always looking for every competitive advantage – a constant hunt for even lighter, stiffer, stronger or more stable equipment. In order to design the best possible drive, every detail of the crankset was questioned and revised. The current XX1 Eagle DUB Carbon crank is the lightest, stiffest and most robust crank yet. The DUB technology optimizes and simplifies the interaction between the crank axle and the bearings and thus improves durability. The DUB cranks have thus become simpler, more universal and more durable.

The SRAM XX1 Eagle DUB crank is only suitable for use with the Quarq DZero XX1 and XX1 Boost power meter spiders. Direct Mount chainrings cannot be used.

Technologies of the SRAM XX1 Eagle DUB Carbon crank


Strength and stiffness where you need them, light weight where you want it. The SRAM design with the exclusive carbon sheathing increases thickness and stiffness in high load areas. The tapered, stepped carbon architecture provides maximum weight savings without sacrificing strength.


Boost is a wheel and drive specification that offers improved frame geometry with shorter chainstays, wider and harder suspension, a greater number of chainring options, more room for wider tyres and increased wheel stiffness and robustness.


The Eagle technology represents the latest 1-speed drive technology. Eagle is a lighter, simpler, more durable and easier to use drive. Eagle features brand new 1-speed components that provide even greater durability and performance while offering a significant weight advantage over other drive solutions. Eagle technology also has an extended 500% ratio range, making it equal to 2x11 drives.


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