Super Record Bottom bracket mayhem! Help! Lol!
I am in the process of restoring a 1983 DeRosa super prestige. All the original parts are present and in good condition. The cranks and drivetrain are Campagnolo Super Record. As I began to “mock up”the bike but I noticed the inner ring was dragging on the chain stay. I also noticed that the bottom bracket cups appeared to be backwards? The side with a lock ring was on the drive side. I don’t have the correct tool to remove that cup so I removed the opposite side and took out the spindle. It measures 110mm and is marked 70 ssa . After doing some reading it seems that super record cranks should have a 115.5 mm spindle for Italian threads. Is this correct? Could it be because the bb is installed backwards that it is rubbing and the 110 mm is correct? It is symmetrical btw! And the crank is marked Strada 1 and is pantographed
Bb for these are very expensive, I don’t want to buy if unnecessary... if you are a campy expert .., HELP! Lol!
