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 SRAM´s 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 deliver simplicity, compatibility and durability.
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 ensures maximum weight savings without sacrificing strength.
The unit consisting of crankshaft and bottom bracket is the heart of the DUB technology. Here stiffness meets durability. SRAM has gone a step further and made everything even easier and better. It's the system approach through the integration of chainring, crank, shaft and bottom bracket that means better drive performance.
