Truvativ Descendant 6k Eagle Dub

The Descendant 6K crankset delivers consistent performance every time out. Featuring SRAM's X-SYNC™2 tooth profile chainring, the Descendant crankset is engineered for complete chain control. Each tooth's thickness is precisely toleranced and controlled to work seamlessly with the SRAM chain's inner and outer links. SRAM DUB™ technology features a better-engineered bottom bracket and a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of durability.Features:- Optimized 6000 series forged aluminum arms- DUB™ technology features a uniform approach to bottom bracket fitment, better sealing against contamination and is forward and backward compatibleSpecifications:- Arm Material: Aluminum- Chainring Material: Steel stamped Eagle™ ring- Weight: 717g (175mm, 32t)- Available Arm Lengths: 170mm, 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™, Eagle™- Options: BOOST™Technologies:BOOST™:- 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 Boost™ compatible components for SRAM drivetrain, hubs and RockShox forks.DUB™ 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-SYNC™ 2 Eagle is the next evolution of SRAM X-SYNC™ 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 EAGLE™ design reduces friction and the accumulation of mud, grit and grime.
