The Descendant 7K crankset delivers consistent performance every ride. Featuring SRAM's X-SYNC2 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 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. - 56.5mm chainline (Super Boost+) - The Descendant 7K crankset is compatible with the SRAM Eagle drivetrain system - Featuring SRAM's X-SYNC2 tooth profile - Optimized 7000 series forged aluminum arms - SRAM DUB technology features a uniform approach to bottom bracket fitment, better sealing against contamination and is forward and backward compatible - Direct Mount ring - ISO 4210 compliant - 12-Speed - DUB bottom bracket sold separately
