I have a 13 y/o Diamondback hyrbrid that the BB separated on me my almost near the house.
I was able to get the chain on the smallest ring and get home.
I would like to replace this as I like the bike but don't know that BB to buy or what special tools I would need. Be gentle with me. I don't want to put a lot of money in this bike and
its the only one I have. All assistance appreciated

Thanks

Ed
