Descendant Carbon GXP Direct Mount Crankset - Boost

With their quality construction and wallet-friendly price tag, TruVativ cranksets have earned a following among riders across the amateur and professional ranks. For this year, parent company SRAM changes things up a bit and gives the TruVativ Descendant Carbon GXP Direct Mount Boost Crankset a bit of a facelift. Updated aesthetics cut a stealthy profile and SRAM's renowned X-SYNC chainring design brings industry-leading chain retention to the TruVativ line. This version bumps the chainline out three millimeters to pair with your Boost-equipped frameset for race-worthy power transfer and confident chain management.

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.
