This is a stupid bike made for the 2009 sea otter classic by members of the engineering department at santa cruz bicycles. It includes two boxxers acting as front and rear suspension, a sram hammerschmidt, a jackshaft and a fixed gear final drive that utilizes two deraillers for chain tensioning top and bottom chain runs. It also has a shocker head tube badge, 900mm wide bars, and a little plastic pig jammed in one of the bottom bracket tubes.
