In the process of getting a road bike and unsure on the frame size. My height is 5 foot 7 and inside leg is 29 1/2". The bike im after has either medium (53cm) or large (55cm). From what I can work out I should be medium but Halfords says a large would be ok. Is this right or are they just after the sale?

Is that a 55cm top tube? I am 5'10, 33" inside leg and ride two 54.5cm top tubed bikes - 53cm sounds more appropriate. What bike is it?

They should get both in for you to try, otherwise I'd be inclined to take my custom elsewhere!

Go to a decent LBS, of which there are many in our mutual neck of the woods. I'm about as tall as Vickster, and on 55-56 cm bikes depending on bike geometry. I can't imagine someone three inches smaller finding the same size frame as me in any way comfortable.
