Found an old German Phoenix bike that had a cottered crank that I want to make into a fixie but the bottom bracket holder has no threads in it.
There are those converison kits on the net but how do I know they will fit?
This would be my first build and I'm quite unexperienced in this game so please answer with care :)
 
Sounds more like an old one piece (ashtabula) style BB. If we have some pictures it may be easier for someone to help.
