Hi! I removed the bottom bracket from a cruiser I recently got and found that it's the kind that has bb's that I'd assume you'd lubricate like a hub. However, the housing ring the bb's would go in is bent so it's no longer straight, so I'd like to replace it with something that would work better.
I've spent a lot of time reading about bottom brackets, so thanks for all the info here. I've determined that I need a 68 x 110.5 mm. And there's also a piece that says 137x24t which I read is the threading.
My questions are, can I buy the kind of bearings that need to be lubricated again, or should I go with a sealed bearing? And do I need to replace everything? The bottom bracket was somewhat difficult to get into because it had rust, and there was some dirt or sand and no lubrication.
I also attached a picture so hopefully my post makes some sense. Thank you very much!
