SRAM Force Crankset - 175mm 2x 12-Speed 46/33t Direct Mount DUB Spindle Interface Iridescent Gray D2SRAM Force Crankset 175mm 2x 12 Speed 46 33t Direct Mount DUB Spindle Interface Iridescent Gray D2. The SRAM Force carbon 2x crankset is the very center of the X Range gearing philosophy. With tight 13 tooth gaps between chainrings paired to wide range cassettes riders get more range while shifting less frequently and staying in the big ring longer. Previously only available on RED SRAMs integrated chainrings are light stiff and incredibly durable.
