Mash it.

Flying under the radar as the less-flashy cousins of parent company SRAM's top-tier crankset offerings, TruVativ cranksets have built quite the fan base of riders and racers looking for high quality componentry at a price that won't break the bank. For 2017, the TruVativ Descendant Carbon BB30 Direct Mount Crankset borrows SRAM's lauded X-SYNC tooth design and gets a bit of a facelift to bring you lightweight power transfer and confident chain retention.

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 trail and all-mountain excursions
  • Carbon fiber construction is stiff, light, and durable
  • Accommodates chainring bash guard
  • X-SYNC tooth design for confident chain retention in diverse conditions

Hard to Beat!

  • Familiarity: I've used it several times

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!

Is there a 170/77 version for fat?
