Bottom bracket with plastic DRIVE side retainer
Hello all,
I am very sorry to be making a duplicate thread, but I made a bunch of typos in the other one and everyone got confused.
I have only one question: are there any bottom brackets with a plastic DRIVE side retainer and metal NON-DRIVE side retainer, instead of the other way around (which seems much more common)?

You wrote that you have such a BB and several respondents said they have seen them. What do you really want?

I contradicted myself several times in that thread due to typos. I wasn't even sure if they understood what I was asking. I think some of them thought I had never seen a plastic cup period.
What I want is to verify that I don't have a bottom bracket that was somehow cross- threaded in backwards, or even less likely a backwards threaded bottom bracket shell, before I go totally nuts trying to remove it. In all my research I could only find plastic NON-DRIVE side cups and wanted to make sure that plastic drive side cups actually exist.

The Shimano LN series sealed BB have a plastic drive side cup . They are just the opposite of all other Shimano bottom bracket units .

I have a bike that had one. It was a bear to take off the plastic drive side retainer. The teeth broke off before it came loose. I'd suggest removing the non-drive side first. I ended up having the break it apart to get it out. Then had to have the threads chased to put in a new one.
Good Luck.
