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 fi
- Unidirectional carbon fiber arm mated to a 4-arm spider with insert-molded aluminum pedal and spindle-interface reinforcements.
- Optimized Q-factor with a 49.5mm chain line and a drive-side integrated GXP (24mm) or non-drive integrated BB30 (30mm) bottom bracket spindle for maximized stiffness.
- The XO 2X10 carbon crankset requires a Sram GXP Team or GXP Ceramic bottom bracket, sold separately.
