size of bike

I have discovered despite what they say, size actually does matter! Im currently riding a Giant OCR 2 size med which I have been told maybe to big. Therefore Im looking at changing pretty soon. Im 5'7 and wondering if anyone could advise me on what size would be better suited?

    Hi Jim,

    It comes now to more than frame size and height I am affraid

    From what I gather inside leg measurement is also important as this determines the length of the crank and I guess the length of torso and arms will play a part in getting adjustments for the handle bars etc.

    I'd suggest going to bike shop and asking there or get a mate who cycles(like what I have done) to help you out with sizing etc

    Other more (bike) worldly wise on the forum will probably be able to offer more specific advise

    [8|]If you go to a bike shop and they don't have someone with the knowledge and the willingness to help you get the correct size - then you are in the wrong shop.[:)]

    Some would question whether you two actually have a job!

    Some of us just can't keep up - i'm not even a junior yet!

    Maybe i'll just have to beat you in the pool

    I have a Giant OCR and it's the 55.5 size, i am 6' so it's likely that you do need a smaller frame

    whereas i works shifts and have access to the net at home and work.

    not sure about this super member bit .. sounds a bit grandiose !!!!

    Think it kicks in at 90...

    Its a fairly amusing concept really....I mean where do we go after 5stars and "super member" (isn't that a porn flick)

    On the question of bike size just to add my little bit I got sized up on a Giant bike and I was told that a small would be best for me although I would probably feel ok on a Medium I'm 5 foot 9 so from that I would think that the medium would be to big however you might have arms that drag on the floor as stated above get fitted correctly at a bike shop and preferably at a bike shop you trust as some will sell you anything as long as they make a few $$$
