Truvativ Descendant Carbon Eagle Dub Boost

The svelte strength of carbon fiber with the swagger of heavy metal. The Descendant carbon crankset uses a proprietary TRUVATIV carbon construction process that delivers a crankset light enough for XC, yet bold and badass enough for Enduro. Style and substance - Descendant. 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 durabilityFeatures:- Carbon construction for lightweight durability- DUB™ technology features a uniform approach to bottom bracket fitment, better sealing against contamination and is forward and backward compatible- Fully compatible with any 1x drivetrain- DUB™ technology features a uniform approach to bottom bracket fitment, better sealing against contamination and is forward and backward compatibleSpecifications:- Arm Material: Carbon- Chainring Material: Aluminum cold forged Eagle™- Weight: 555g (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.
