This post further documents Sean “Burnsey” as he progressed through his recent Fat Bike Frame Building Course at Metal Guru. The frame he chose to build was a single speed 29″+ that will fit a 29″ x 3″ tire. Other features include sliding dropouts, 44 mm head tube, bent down tube, short chain stays and a bent seat tube. The gallery below shows the steps he took from tack welding through to the finished frame. To see his initial efforts check here.
