I think the problem is you may think a 1997 is an old bike but many of us would not consider it old. I thought you were talking aboout a freewheel bike when you said old and that would be considerably more involved and expensive. When you ask question give all the information you can. Your question isn't as bad as the ones that say "I have a red bike what is it" but you would have gotten better answers with more details. Roger
