Thanks to everyone for there excellent advise. That sure opens my eyes a lot now. The bikes that I am starting to do now as a hobby are bikes that people give me. I fix them up and give them away to a church or others that need a bike. I don't get high end bikes. Mostly Canadian Tire and Wal- Mart type bikes. Although I do have one that is a Trek but don't know much about that one. So you see I get all sorts of bikes here and there and put as little money into them as I can, BUT I also make sure that they are in top notch condition before I give them away.

Thanks...Greg
