I converted my first bike into a single speed last week (already have a fixed and wanted to see if I liked the single speed side -- I didn't). Anyways, I had the frame lying around because I wrecked it years ago and it just was sitting in my shed, and I had a few parts lying around so I fixed it up and it ran great.
So now I'm looking to convert another bike into a fixed and was wondering where you guys are getting your frames? You guys just have these things lying around? Buying old roadies off CL and flipping them? Dumpsters? Ideas?
