Product Description The Descendant 7K crank offers consistent performance every time. With SRAM's X-SYNC™ 2-tooth profile chainring, the Descendant crank is designed for complete chain control. The thickness of each tooth is precisely controlled to work seamlessly with the inner and outer links of the SRAM chain. SRAM DUB™ technology features a better developed bottom bracket with a new axle design. Together, they allow for a more consistent approach to bottom bracket fitting, a better seal against contamination, and upward and downward compatibility. Now everyone can benefit from a new level of durability.

Stiffness meets durability. SRAM has gone a step further and made everything even easier and better. It is the system approach through the integration of chainring, crank, shaft and bottom bracket that is decisive for better drivetrain performance. X-Sync 2: X-Sync 2 Eagle is the latest evolution of SRAM X-Sync™ technology. The tooth profile of the chainring increases the chain tension and efficiency when pedalling. The life of the chainring is longer because X-Sync Eagle technology reduces friction and dirt.
