I am looking for a square taper 136mm width spindle bottom bracket for a 1980's Diamondback.
I cracked the original spindle and this one is in there now, but it is not wide enough, so the small ring was rubbing on the frame and I had to remove it. Since then, the chain has dropped twice causing me to fall kinda bad.
So I either need to find the proper bottom bracket, or come up with some kind of custom guide to keep this chain on. I don't mind running the single ring up front. Keep in mind they are biopace rings. Thanks
