Description
 SRAM XX1 Eagle DUB SL Crankset
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. SRAM 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.

Technology
BOOSTâ„¢
With revolutionary advancements in bicycle componentry, like SRAM’s XX1, X01 and X1 drivetrains, mountain bike designers have been given almost limitless freedom to focus solely on the performance of the bike. Each advancement demands that the entire package works flawlessly. Aggressive trail and enduro riders have been increasingly enjoying the benefits of larger wheels, but many still view 27.5″ and 29″ wheels as a possible weak link. Which is why SRAM has developed an open standard with Boostâ„¢ compatible components for SRAM drivetrain, hubs and RockShox forks.
CARBON TUNEDâ„¢
Strength and stiffness where you need it, lightweight like you want it. Proprietary SRAM carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.
DUBâ„¢ Technology
The relationship between bottom bracket spindle and bearing is the core of DUB™ technology. It’s where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler — and better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this clear system approach that equals better drivetrain performance.
X-Sync 2
X-SYNCâ„¢ 2 Eagle is the next evolution of SRAM X-SYNCâ„¢ technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC EAGLEâ„¢ design reduces friction and the accumulation of mud, grit and grime.
