    the 26 and a bit. it will say on it what size it is.

    the clamp size is not the same as the seat post size.

    then have a look in the FAQs for a good way to get the right info. as you do need the correct size post.

    Vernier callipers will tell you the ID of your seat tube and the OD of the current post, but 27.2mm is probably the most common for a 31.8 clamp size.
