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. Their 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.X-Sync 2 SRAM X-Sync 2 Eagle is the next evolution of SRAM X-Sync technology.

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.
