The crankset/bottom bracket that came on my bike ('12 Jamis Dragon Sport 29) is a SRAM S800, 44/32/22, 175mm with a SRAM GXP integrated bottom bracket. The outer ring (at minimum) is aluminum. I can't seem to find the weight of the entire crankset/BB/spindle anywhere with Google, and I'm trying to figure out if this is a place I should be looking to drop some weight. I'd be staying with a triple regardless.
