    Trouble installing new bike seat, trouble with seat post clamp and saddle rails

    I am kind of a bike newb, but I am trying to replace the old hard seat on my bike with a wider, softer seat.

    The seatpost with my bike is a 28.8mm Kalloy seat post, the kind with a single bolt clamp at the very top that is supposed to clamp down on the rails of the bike seat.

    I bought a new bike seat (link: http://www.amazon.com/Sunlite-Cloud-...7196691&sr=8-4) that is wide so it won't hurt my butt as much.

    The rails underneath the seat seem to be just a few centimeters wider than the clamp grooves, so that the rails of the seat cannot fit snugly within the grooves of the clamp.

    I am curious about what I can do about this besides buying a new seatpost/clamp, and even if that would do any good. Is it common for seat rails to be different distances apart from each other? Is there anyone that makes a 28.8mm seatpost besides Kalloy? It might be easier if I could get one that is just a pole that narrows toward the top, instead of messing around with the clamps. The last thing I want to do is buy another seat post and find out the the clamp grooves are still too far apart.

    Thank you very much for your time

    I've had to squeeze the rails to get 'em in there before.

    It may just be millimeters. Anyway, I think I will probably have to squeeze it in.

    Is there any particular technique to this or recommended tools? I tried using a set of pliers and the only thing I have managed to do is scuff it up.

    Pair of vise grips/channel locks & a little pressure. Test fit until you get the right distance between the rails.

    just muscle i think.
    maybe wrap a shoe string with a stick at the end around the rails and twist the stick til the rails move closer together?
