Product Description
This Truvativ X0 GXP 2.2 10-Speed Crankset uses carbon fiber like the top shelf XX crank, but there are a few differences. Unlike the XX crank, there's no alloy spine connecting the threaded pedal insert and the crank/spindle connection. SRAM engineers figured out a way to eliminate it, instead using a stiff structural foam core inside the composite skin. SRAM's goal for XO was to make it burly enough to handle the rigors of all-mountain riding. Another difference is that this XO crankset uses an aluminum spider where the XX spider is an integral part of the carbon crank arm assembly. While it's a few grams heavier, the XO system allows you to remove the spider if you want to change from two to three rings or vice versa. As is, this 2x10 setup has a bolt circle diameter of 80/120mm. Of course, it's an exclusive measurement, but for the chaining tooth combinations SRAM wanted to offer, it optimizes the stiffness of the rings. And stiffer chain rings mean quicker, more precise shifts.
