  • I am putting together my first build. I have a wheel with a Miche hub. The frame came with a bottom bracket for a cottered chainwheel and I thought, for the sake of convenience and expense, I would stick with that BB and buy a new 46t chainwheel.

    I have only handtightened the chainwheel but it looks like it will rub against the chainstays (see red ring in photo below). This may have been a problem for the previous owner as the paintwork is marked at this point.

    It seems to me that I am probably going to need to get a new BB (the chainline is not so great with the present set up either) so my two questions are:

    • does anyone have an alternative suggestion for solving this?
    • does anyone have any good advice for finding a suitable BB?
