XX is SRAMs premier 2x10 XC racing componentry and the crankset is where it all begins. All efforts are focused on performance and saving weight wherever possible. The driveside crankarm and spider are one piece that is constructed from a carbon-alloy matrix with a foam core. This design helps keep the weight down to the amazing mid-600 gram range. The chainrings are mounted to the inside of the spider keeping the Q-factor down to a scant 156mm. This in turn tightens up the chainline and greatly improves shifting. Oversize alloy Torx bolts fasten the rings on the spider. The rings are SRAM's proven X-Glide and have any bit of non-essential material shaved off via a CNC mill. Plenty of pins and ramps make the front shifting quick and accurate.
Simply put, this is a no frills, lightweight XC race crank that is also durable enough to be used as an all mountain crank if you prefer 2x10 on your rig. We carry the XX crank in 26/39t gearing as it is now becoming industry standard for any type of riding. The crankset will require a SRAM/Truvativ GXP bottom bracket which is not included.
