Sram Xx1 Eagle Boost Dub Direct Mount

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, we re-examined and re-engineered our crankset design. Our all-new XX1 Eagle™ CARBON TUNED™ crankset is our 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.Things To Remember:- Eagle™ represents our newest 1x drivetrain technologies- Eagle™ is a lighter, tougher, quieter, more durable and more precise drivetrains- Eagle™ features all-new 1x components, engineered for even greater durability and performance- Eagle™ has a significant weight advantage over other drivetrains- Eagle™ technology allows an expanded, optimum, 500-percent gear range — a 20-percent increase over our other 1x- Eagle™ is a complete drivetrain system that was developed to be an integrated high-performance ecosystem. The engineering and testing that went into the development provide for maximum performance, safety, and long-term durability to ensure a great consumer ride experience. We guarantee this performance when Eagle™ drivetrains are used as a complete ecosystem.
