The SRAM XX Q166 GXP 10 Speed Chainset delivers amazing performance and durability with no penalties in weight. The first MTB crank specifically designed for 2×10 uses some of the world’s most advanced material science. The oversized chainrings are CNC machined form 6mm 7075 aluminium blanks – 2mm thicker than the competition. Unparalleled stiffness is delivered by an increased Bolt Circle Diameter (BCD) and a two-piece insert moulded carbon composite competition. The XX crank geometry provides a narrow 156mm Q factor, efficient chainline and bevelled crank arms to maximise clearance. It’s pure science in action.


GXP is different – and better. Other systems rely on side-load bearings to eliminate play, causing bearing wear. GXP captures the left-side bearing between the spindle and the left crank arm and allows the drive-side bearing to float axially on the spindle. There’s no need to side-load bearings during adjustment. No excess wear and a much simpler installation. Just tighten to the proper specifications and you’re ready to roll, worry-free. GXP’s two bicycle-specific cartridge bearings and eight seals ensure a smooth, long-lasting ride. SRAM’s new gutter seal system takes a two stage approach in directing contaminates away from the bearings providing longer bearing life.
