Sram Xx1 Eagle Dub Boost Direct Mount Crankset Black 170 mm / 34t

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. DUB™ technology delivers the lightest, stiffest, strongest crankset available. All-new SRAM CARBON TUNED™ crank technology provides extreme stiffness and light weight. The X-SYNC™2 chainring provides significantly quieter performance, with better mud clearing and extraordinary durability.Specifications:- Arm Material: Carbon Composite - Hollow Core- Chainring Material: Aluminum Cnc Eagle™ Sl- Weight: 422g (175mm, 32t)- Arm Length: 175mm- Compatibility: All Levels Of Eagle™ Drivetrain Systems, All Major Bottom Bracket Standards.- Bolts: Direct Mount- Recommended Chain: Eagle™ Chain Only- Technology Highlight(S): X-Sync™2, Boost™, Carbon Tuned™, Eagle™
