Here goes, When sizing a bike in cm, such as a 54 cm frame, what is being measured.
For instance, my old bike is an 18 inch frame, the seat tube is 18 inches long. But if you convert that to cm it would be 46. Now my wifes bike is a 50 cm frame, and it is way to small for me. So my question is what does that 50 represent?
This is something I really should know already, but I don't.
Asbestos under pants are on.
Size from manufacturer to manufacturer and sometimes even in product lines within a specific manufacturer are not directly comparable. Or, so say several dealers and mfg reps. From personal experience I know that from three different manufacturers I take three different sizes for bikes that fit. So, there is only one way to know what the right size is for you; ride the bike.
It is your money and your fun. Spend it as you wish. Just ride whatever you are thinking of buying enoiugh before you buy to have a reasonable chance of being happy with your purchase. Oh yes, don't worry about the Bike Snobs who think you have to dress a certain way or wear certain clothes, have certain equipment, or whatever. It is your ride, not theirs.
