• wheels Sounds like you have a 68mm BB shell and not a 73mm BB shell . . . or the shell has been 'faced' once or twice by an over zealous mechanic.

    . . . nothing to worry about if it is only two or three threads, once you have plenty of threads in the shell + it all turns nicely + there is no play then it shouldn't be a problem.

    Here is a great thread over on BikeForums about Sug75BB installation - you probably don't need it now, but the bloke who did it did lots of nice photos so it is a great guide ! :)
