I have an old mountain bike frame (92 ish Giant ATX 770) that I was considering converting to fixed a couple years ago. I’m reconsidering because finding the magic ratio is a pain and I think I’d rather just do a SS with a tensioner and be done with it. I installed the Fixxer a while ago and want to remove it, but I can’t get the actual threaded alloy body out of the hub for the life of me. I’d rather not damage it as it’s unused and I might keep it around for a future project or sell it.

Does anybody have any tips for removal of the threaded alloy body?

Thanks.
