Another boring BB question -- Need your thoughts
I am building up a 1994 Serotta TG. I have an extra cup style BB from a 1989 Trek 660 that I want to use. I know very little about BB threading and and compatibility, and want to be careful with this. I tried by hand screwing the non drive side cup into the Serotta and meet significant resistance. The cup is Japanese and is marked 1.37"x24T. Does anyone know, off hand, whether this cup should fit the Serotta?
Never mind, I put a little "wrench" behind it and it went right in.
