I have a 2001 Lemond Zurich frame set that I have had for years collecting dust. I've decided to put it back together. I am looking to switch it to Campagnolo. I need help with the Bottom Bracket. The LBS told me it was a BB30 English thread but that does not seem to match what I am measuring. I pulled out a Shimano BB-5500 68 BC1.37x24
I know the shell is 68mm. Inside of the shell to be BB30 should be 42mm correct? I very likely and just measuring something wrong but am getting in the 30mm range.
I am looking at getting the press in cups so I don't have to replace the bearings on the cranks. Can I do that? Do I have to replace the bearing and get the thread in cups?
Campagnolo OS Fit BB86-BB92 86.5x41 Ultra-Torque Press-Fit
Campagnolo BB30 Ultra-Torque Press-Fit 68x42
I could be off on both. Any direction would be great!
