    Standard advice would be to demo a few sizes and see wha fits best. I'm sure there are sites with recommended sizes. I'm 175cm and ride a 56cm if that helps.

    My general rule of thumb is... you should be able to stand of the cross bar with about an inch to spare.

    I'm 174cm in height and take a 54cm road frame for around a 4-5cm standover height....

    You're 168cm in height, and they sold you a 49cm frame....

    174-54 = 120
    168 - 49 = 119

    Close enough for me at a ready reckoning, would you not agree?

    Of course, you are no doubt aware that the standover height on a compact/sloping geometry frame will be greater than a 'tradional' frame with a horizontal top tube, aren't you? Which would mean that if your top tupe is sloping, your standover height would be an extra couple of centimeters.... Just like you describe....

    To be honest, you sound like you're getting your cacks wrapped round your nick-nacks, over nothing.

    If you've a problem with the sizing, complain to the bike shop...And then kick yourself a kick in the hole for listening to your know it all mate who suggests you need the non-existant frame size of 53.5cm.....Unless you're dropping a G at least on a custom frame....

    Pure genius.... :p

    Don't worry too much about the standover height of the bike - it makes no difference when you're riding. The important thing is that you're comfortable on the bike. Have a read of this article:
