So, I have two bikes. They were 10 speeds. I took off all things shifting, and I still plan on turning one into a single speed(they both have cassettes, but no ability to shift because I'm cheap). The only problem is that I only need one project bike. Oh, and one of the rear wheels keeps popping tubes. So, I might be looking to give away one of them. I am keeping the one with the huge frame, as it fits me better than the normal sized frame bike. I also have a box of parts if you want to return it to 10-speed form. I kept everything from both bikes that I took off.
The only problems I can think of is the need for a new bolt to tighten down the handle bars, and some kind of fix to make it not pop tubes(I've blown like 6, and even when a shop puts them in they still blow. It has me really confused.) So, yes, you can be my vintage Schwinn twin. Good times indeed. Let me know if you are interested and I will sort things out quicker in preparation for it's departure. If not, I might just turn it into a Dandy Horse.

If that doesn't work out, I'm gonna put it on Craigslist as a "Possible Mad Tite Fixie Dawg" so some Broseidon can skid it into a car and out of my sight. Actually, I could probably make some money that way.
