My bb vaguely looks like this.
The problem is, the two large rings on the side. I have one that screws on clockwise and one on counterclockwise. I surmised that the drive side bb should thread on clockwise. However it seems to only want to thread halfway into the shell, then it seems like I really have to force it before it budges (didn't do it).
The weird thing is if I try to thread the same ring on the other side, it goes in fine. But then i'll have two rings that will unscrew itself from pedalling motion?
Am I missing something obvious again?
It's my 87 bianchi once again.
P.S are the outer lock rings necessary? Or can I just leave them off.
