I disagree. Compact and standard frames do not really dictate fit. Measuring the actual tube lengths on different frames is a bad way of sizing a bike, and the reason people freak out about compact frames. You have to measure like-for-like. If you measure the length of your top tube on a standard frame on the horizontal, you need to compare that to the 'virtual' horizontal top tube length of the compact frame. Otherwise you are looking at different angle in relation to the seat tube.

Another way of thinking of it. Curved vs straight bladed forks. You can achieve the same steering geometry either way. Its just how the tubing gets from point a to point b that changes.
