Coming in at 754 grams, 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!
