    Modifying a carbon seat post

    Hi all,
    New member here.
    I'm shopping for my first road bike. My local shop has a real nice used 2012 Giant TCR Advanced, full carbon/Dura Ace for $1500, but it's a 61cm and my feet can barely reach the pedals.

    The seat post on this bike is integral to the frame with very little adjustment on the saddle. I'm wondering if it would be crazy to cut the post down a few inches to make it a 58cm (which is the size that felt right when I test drove a few others). Or, are there other factors involved like the handlebars and rest of the frame?

    It's hard to find a good used bike these days as there's a lot of demand.

    Thanks.

    Cutting a seatpost itself is not crazy. But cutting it for your purpose is. DON'T!!
    There's much much more than the seat height that determines a correct bike size.

    What TLG said is 100% correct. Trying to make the wrong size fit is never a good idea. It's a "good deal" partly because it's an odd size which is hard to sell.

    Keep looking. There will be other good deals out there in your correct size.
