The Heavy Hitter is as tough as they come. It had to be to be called the Pat Laughlin Signature Model. The frame is 100% chromoly, with a double-butted mainframe, externally machined-BB, removable brake mounts, and heat-treated bottom bracket, head tube, & dropouts. A serious parts package includes 48-spline 175mm cranks, tapered forks, Odyssey pedals, sealed hubs, female front hub, CNC lightweight stem, & Tioga tires, which means the Heavy Hitter is ready to rock and roll. All you add is 100% commitment. 24lbs.
