Race-day approved.

The TruVativ Descendant Carbon BB30 Direct Mount Boost Crankset gets a bit of a facelift for 2017, with parent company SRAM infusing its venerable X-SYNC chainring design and refreshed aesthetics. It retains the quality construction and budget-friendly pricepoint we've come to expect from TruVativ to bring impeccable chain retention to your next ride. This version bumps the chainline out by three millimeters to pair with your Boost-equipped frameset for confident chain retention and race-ready power transfer.

Carbon fiber arms interface with aluminum direct mount chainrings for a resulting lightweight crank arm that doesn't require a finessing of parts in order to make an optimal single-ring setup. The X-SYNC chainring is designed for maximum 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 and chainring essentially lock together as you pedal. However, the locking of the two doesn't inhibit pedal efficiency, and it eliminates the commonplace ailments associated with running a single-ring up front.

The direct mount chainrings also afford the option of quickly subbing different sizes of rings for different shapes of terrain, giving the true all-mountain racer a bit of race-day flexibility to adapt to a given course.

  • Stiff, durable crankset for all-mountain and trail excursions

Hard to Beat!

  • Familiarity: I've put it through the wringer

Descendant has been working with Sram for a while now and have come a long way. You can even find them on some higher end builds from companies like Transition and more. For the price point it's hard to say you would be getting a lot more with the standard XO cranks. It's a happy medium between the lightness of the foam core XO model and the strength of the aluminum GX model. The eagle compatible chaining makes it a great option to mix into your XO build which is what I did. Love it!
