    Single Speed Frame Size

    Judging by the length of the seat posts of most SS/fixed bikes, do the guys riding them buy smaller frames? On my road bike, my crotch barely fits over the top bar (I was told that it was the proper size.) so my seat is pretty low...

    The primary measurement is the top tube and cockpit length.
    This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.

    People ride smaller frames because A.) they get to raise the seat, B.) which makes them look like teh tracksters!1!
    Next ten people will post saying 'that's not true', but nine of them will know it is.

    I don't want to have a head on but oh god, I HAVE to fling myself into oncoming traffic to pass, theres no alternative!!!

    It's not just the single speed track frames - it's all modern "compact" frames that end up looking like that. When there is a sloping top tube, the traditional standover measurement means nothing since the seat post starts much lower than it would with a level top tube. And the results is miles of seatpost sticking up to get the right seat height...

    One of my bikes is 60cm,(attached file) and still has a good length of seat post to make the saddle height correct.
    I have another bike that's 57cm, sloping top tube, (see link) with a mile of seat post. They both seem to fit me well but I have never had a pro fitting, just go with what feels right.
