Maybe you already know this, but Truvativ is SRAM's mountain bike crankset and bottom bracket company. that's right, there's no such thing as a SRAM mountain crankset. Rather, with Truvativ you get SRAM's signature high-quality, high-technology, and high-value designs. Regardless of your intent -- a bomber crankset for an all-mountain bike, or something featherlight for a cross-country bike -- Truvativ cranksets and bottom brackets proudly carry on SRAM traditions.
