What matters most to hardcore mountain bikers? Performance, durability, affordability, and style. TRUVATIV's new Descendant series serves up all of these with confidence to spare. Guided by input from some of the most talented riders in Enduro and Gravity, each component in the Descendant lineup has been built to survive mountain biking's most aggressive riders and thrive on the world's rowdiest trails.
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. DUB™ (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 52 mm Boost (148 mm OLD) chainline.
- oversized DUB spindle to work across every bottom bracket standard
- less weight with direct mount SRAM's X-SYNC™ 2 ring
- Very affordable carbon crankset in the industry
- Carbon construction for lightweight durability
The radical look and feel of SRAM's X-SYNC™ 2 Eagle™ chainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC™ 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 Eagle™ drivetrain's performance in all conditions. The longer, positive-rake tooth shape has been designed to work perfectly with the new Eagle™ 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-SYNC™ 2 design increases chain retention and wear life, and reduces friction and noise.
DUB™ (Durable Unified Bottom Bracket)
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.
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.
