Message: >I have purchased a new Serotta Ti frame. I have an old Litespeed Ti. I wanted to transfer my groupo from the old bike to the new. However, I was told by my LBS that my old BB would not be compatable with my new frame's shell. >I have they changed the standard size of the english BB? .............to my knowledge ,the old Lightspeeds and new serottas both english threading, amd the BB should switch frames ok. Ask bike shop for more specifics on their position and if they can't support it, with real facts, look for new bike shop. They may just want to sell you a new BB....IMO. You did not say if you frame is mountian or road?? Typically, the serotta or lightspeed road frames would have english threading with a 68mm shell width. However, mtn bike frames would have english threading with a shell width of 68 OR 73mm. Maybe this is the difference??
