Descendant Carbon Crankset
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. DUBâ„¢ (Durable Unified Bottom Bracket) technology features a better-engineered bottom bracket and a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment and better sealing against contamination. Now everyone can benefit from a new measure of durability.
Version for 49 mm standard chainline.
- oversized DUB spindle to work across every bottom bracket standard
- less weight with direct mount SRAM’s X-SYNCâ„¢ 2 ring
- Very affordable carbon crankset in the industry
- Carbon construction for lightweight durability
The radical look and feel of SRAM’s X-SYNCâ„¢ 2 Eagleâ„¢ chainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNCâ„¢ chainrings. They subjected every size of chainring to untold environmental and mechanical tortures, abuse and neglect, in both lab and real-world settings, to come up with a chainring that would augment the Eagleâ„¢ drivetrain’s performance in all conditions. The longer, positive-rake tooth shape has been designed to work perfectly with the new Eagleâ„¢ chain to increase chain retention and overall pedaling efficiency, while decreasing friction, noise and wear.
- Compatible with 11- and 12-speed drivetrains.
- Designed specifically for Eagle chains and drivetrains.
- X-SYNCâ„¢ 2 design increases chain retention and wear life, and reduces friction and noise.
DUBâ„¢ (Durable Unified Bottom Bracket)
DUBâ„¢ 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.
X-Sync 2
X-SYNCâ„¢ 2 Eagle is the next evolution of SRAM X-SYNCâ„¢ 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 EAGLEâ„¢ design reduces friction and the accumulation of mud, grit and grime.
