Tonight I started cleaning and polishing the handlebar hardware. I was surprised to find that the handlebar clamps are actually cast aluminum. They had been painted black but I thought they would look better polished next to the chrome bars. I also pulled the wiring out of the old handlebars, getting a blister in the process. The 35 year old plastic tubing around the wires is very stiff. I will probably have to rewrap them in order to feed them through the new bars. I also quickly cleaned and polished the old handlebars. Hopefully someone will buy them on Ebay.
