Okay this is weird but in putting this back together it came to my attention that there is no lock ring on my new BB. Even more odd is that I took the old one out to compare, and it doesn't have one either. I dug through the old parts box, and the new parts box and none to be found. Apparently it came this way, and I was riding it this way, but is it like, bad? Is it going to fall all apart on me?
