DESCENDANT 7K DUB™ Crankset

New

Description

The Descendant 7K 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.

Technology

BOOST

BOOST is the standard wheel and drivetrain specification that opens the opportunity for improved frame geometry with shorter chain stays, wider and stiffer suspension pivots, wider range of chainring options, as well as more clearance for bigger tires and wider, stiffer wheels.

Eagle

Eagle technology represents our newest 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 520%, which is equal to 2x11 drivetrains.

X-SYNC 2

SRAM 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 2 Eagle design reduces friction and the accumulation of mud, grit and grime.

DUB

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—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.
