The TruVativ Descendant Carbon Eagle DUB Crankset, sees a bit of a facelift this season, with parent company SRAM bestowing it with newfangled DUB technology. DUB technology features a newly-engineered bottom bracket and an optimized spindle design. This allows for superior fitment and better sealing against contamination and is the intersection of where stiffness meets durability, with no compromises. By better integrating the relationship between the chainring, crank, spindle, and bottom bracket you'll get a better performing and longer lasting drivetrain. You'll have to use a new DUB bottom bracket with this crank but the good news is it's backward compatible with existing frame designs. This means more time on the trails and less time troubleshooting creaks and worn out components. The Descendant Carbon is the same quality construction and wallet-friendly price point we've come to expect from TruVativ that's light enough for XC yet burly enough for enduro.
Carbon fiber arms transfer the power from your legs into the aluminum direct mount chainrings creating a lightweight crankset that is ready to go out of the box with a single-ring setup. The X-SYNC chainring maximizes chain control, with each tooth CNC-machined to support the chain's inner- and outer-links. This machining process provides a variable thickness from tooth-to-tooth, so the chain is essentially locked onto the chainring preventing it from jumping off over rough terrain.
Direct mount chainrings also allow for quick swaps to different size rings if you have a big mountain enduro one weekend and an all-day backcountry epic the next.

Worth the money
I've had this crank on a couple different bikes now and have been quite impressed with it. For the money, it's pretty light, holds up to a lot of abuse, and looks good on the bike. The DUB platform helps save a bit more weight off, while still seeming plenty stiff for your average rider. I usually put the small crank boots on the arms to keep marks from pedal strikes at a minimum.

- Familiarity: I've put it through the wringer
I have this crank on a couple bikes now, and a couple previous. They are priced really well for a carbon crank and have held up through much abuse. They look great and perform every bit as well. Highly recommended.
