Bought a road bike (1980 something, unknown brand, model name 'Performer', lugged frame, Suntour 7 group) a few months back and have been slowly replacing the components piece by piece.
One of the pedals fell off the other day and I saw that the threads on the crank arm were stripped. Replacing the crankset, gears, front and rear derailleurs and shifters is on the to-do list anyway, so no problem. Only thing is, the bottom bracket is a odd one. Shimano Selecta, made from '78 to '80 or so, from what I can tell. And what I'm stuck on is what exactly I can put in its place. The cups are threaded in, but it seems to have rusted on to the point of resisting anything but a hacksaw.
So my question is, what is known about this bottom bracket / crankset and what square taper bottom bracket can I replace this with?
