How do I know what size front mech to buy?

My seatpost is 27.2. I presume that if I was to buy a seatpost clamp it would be 28.6, so does that mean then that I need a 28.6 front mech clamp. or do I buy a 31. one and use a shim?

  • well.... measure it?

    piece of string + a ruler is a fairly simple way.

    never presume as invariably it is wrong.

    you clamp will br one of the 3 standard sizes. or a direct mount or an E type mount.

    but that all depends on the designer of your frame.

    So what is it? make, model and year.
