So I got a mid-80s daccordi frame that I figured my campy record (1990) bottom bracket would work with, but that's not the case. Before bringing it to the shop, I just tried to thread it into the shell so I could just carry it in like that, however the bb diameter is too small-- it basically just falls into the shell.
I don't know much about bottom brackets and I'm having a little bit of trouble learning. The dimensions on the bb are 1.37 x 24t, which is english correct? And this would also make the diameter smaller than my italian bb shell?
And if this is the case, any new bb recommendations would be appreciated (I have the whole 1990 record titanium group, so the new bb would have to be compatible with the same cranks as this one).
