SRAM XX1 GXP Direct Mount Crankset 156 Q factor

SRAM's XX1 GXP Direct Mount Crankset achieves a low 156 Q factor by taking advantage of two of the crank's essential design characteristics: spider free mounting and a single chainring. The result places the pedals over a centimeter closer to the bottom bracket than they'd be on a 168. Though that may not seem like much in the vacuum of a tech spec sheet, that centimeter can feel like miles when the extra clearance provides a bit more room for error on the ragged edge. Except for the narrower profile, this crankset features the same lightweight, carbon stiffness of the wider model. The standard XX1 chainring to chain redesign returns unchanged, featuring a pattern of widenarrow teeth with tall, square edges to maintain early, confident engagement for popping up rocky climbs or dropping the hammer in a finale. The direct mount version also affords the option of quickly subbing different sizes of rings for different shapes of terrain, giving the true all mountain racer a bit of start line flexibility to adapt to a given course, and SRAM's GXP design uses a 22mm gutter on the non drive side to reduce friction and weight without sacrificing the drive side's power transfer.
