Descendant Carbon Eagle DUB Crankset - Boost

What Our Gearhead® Experts Are Saying:

"I’ve ridden this crankset on both hardtails and full-sus builds, and it punches way above its price point. The carbon arms are noticeably stiffer under load, and paired with the DUB BB, everything feels smoother and better sealed. It’s been a bombproof option for rocky, wet rides."

The Truvativ Descendant Carbon Eagle DUB Crankset brings premium carbon construction to riders who demand durability, stiffness, and value. Designed around SRAM’s DUB standard, the spindle works across nearly every major bottom bracket format, including BSA threaded, BB30, and PF30. This improves bearing sealing and longevity, making it an ideal setup for riders tackling wet or muddy terrain.

Truvativ’s carbon fiber crank arms offer increased torsional rigidity while reducing weight, enhancing power transfer and pedaling efficiency under load. The included 32T X-Sync 2 direct-mount chainring delivers improved chain retention and a smoother pedal stroke, especially on long climbs and high-speed descents. Boost spacing ensures optimal chainline and drivetrain performance for modern trail bikes with wider rear axles.

Fully compatible with any level SRAM Eagle 1x drivetrain—from GX to XX1—this crankset is a high-value, high-performance option for trail, enduro, and aggressive XC riders looking to upgrade from aluminum cranks without jumping to top-tier pricing.
