Sram: LIGHTER. STIFFER. STRONGER.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 mean 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 1xFEATURES AND BENEFITS• DUB™ technology delivers the lightest, stiffest, strongest crankset available • All-new SRAM CARBON TUNED™ crank technology provides extreme stiffness and light weight • All-new chainring technology is designed specifically for Eagle™ chains and drivetrains • The X-SYNC 2™ chainring provides significantly quieter performance, with better mud clearing and extraordinary durabilitySPECIFICATIONSSpeeds: 11/12BB Compatibility: BSA 68/73, PF89.5, PF92, PF30 MTB73, BB30 MTB73Chainring Size: 34Crank arm length: 170mm, 175mmChain line: 52.0mmBB Spindle Interface: DUBChainring material: AluminiumGuard: No GuardBolt Circle Diameter (BCD): Direct Mount (DM)Crank arm material: CarbonColour (Crank arm): Black, Gold
