This stunning, all carbon crankset sets a new benchmark in lightweight, performance XC componentry, delivering a rock-solid feel underfoot. Broad, hollow carbon crank arms feature an integrated, drive-side, CNC machined chromoly bottom bracket, permanently molded into the crankarm to minimize weight and maximize power transfer. The 7075 aluminum chainrings maximize wear resistance and feature S.H.I.F.T. technology for lightning quick shifts. Redesigned bottom bracket uses a triple wiper sealed cup to keep water and grit from contaminating the sealed cartridge bearings packed in Phil Wood waterproof grease. Co-molded pedal and spindle inserts are mechanically locked into place so they'll never loosen or creak. 44/32/22T. 730 g.

Coming in at 694 grams (BB30), the Sram XX Crank delivers amazing performance and durability with no penalties in weight. The oversized chainrings are CNC machined 7075 aluminum blanks-2mm thicker than the competition. Unparalleled stiffness is delivered by an increased Bolt Circle Diameter (BCD) and a two-piece insert-molded carbon composite construction. The crank geometry provides a narrow 156mm Q factor, an efficient chainline, and beveled crank arms to maximize clearance. Patented X-Glide chainring technology delivers accurate, lightning fast front shifts.

The development concept for X-Glide was simple: create a geometry that allows each chainring to be divided into equal segments, much like a pie. Then, perfect the up-and downshift timing for one segment, and repeat that for each of them. With X-Glide, all four upshift locations are identical and can be picked up by any outer link. The result? Up and down shift locations have perfect timing, for an almost instant shift-even under load!

All new Truvativ PressFit 30 bottom bracket debuts with XX. Light and strong, the all-new PressFit 30 provides big weight savings, a narrower Q factor, and more ankle clearance in an easy-to-install, durable little black package. PressFit 30 features an integrated gutter seal underneath an aluminum-bearing shield to dramatically prolong ceramic bearing life.
