So I got this bike out of the trash. Did some research and found out its a 1980 Sanwa 110 10 Speed. I loved the look of the bike but multiple speeds aren't my thing. So I tore the bike down repacked the bearings, new tubes and tires and new brake cable. I drilled out the rivots on the original crank sprockets cut the larger sprocket off of the crank and bolted the smaller sprocket to the crank with stainless hardware. I added a spacer in the rear and a threaded freewheel to convert it to a single speed. I also changed the bars and grips and brake lever to make this a fun bike to commute with. I tried to keep the bike as original as possible but make it my own. Let me know what you guys think.
