I know it’s an old thread, but since it’s been resurrected, I just wanted to add my 2 cents. With the advent of the TV show American Pickers, suddenly everyone and their neighbor thinks that old rusty bike or frame in their garage or back yard is a gold treasure. Even if I wanted to restore a bike, the cost of and rarity of some of the parts would make it unprofitable. Building or restoring bikes is like restoring or building a hot Rod car. You build it for your own pleasure, because more than likely you won’t make a big profit if at all when you sell it. Rat On !!
