Which I'll ask here because I hope to be flamed less than the other forums.
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.
