Truvativ XX BB30 2x10 Crankset 2013
Truvativ's BB30 is the first MTB crank specifically designed for 2X10. With oversized chainrings that are CNC machined from 6mm 7075 aluminum blanks-2mm thicker than any other competitor. Extreme stiffness is delivered by the increased Bolt Circle Diameter (BCD) and a two-piece insert-molded carbon composite construction. The XX Crank geometry provides a narrow 156mm Q factor, efficient chainline and beveled crank arms to maximize clearance.
