1986 PX-10 Bottom Bracket Specs Needed - Solved
OK... Been going around and around on this. I have what I believe is a 1986 Columbus Tubing PX-10 Frame that I want to fit out with a sealed bottom bracket. Its 68mm and on inspection has an English Thread @ 24G with the Fixed threaded left. So I am assuming I can just order an English square taper 68mm sealed bottom bracket at 120mm. I am going to use a double compact crank. Did the original PX-10 come with 110mm, 120mm, or 125mm spindle length? I have been searching for the specs but cannot find them.
