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
  • Stiff, light, and durable carbon fiber construction
  • Accommodates chainring bash guard
  • X-SYNC tooth design improves chain retention in diverse conditions
