Partially correct?...lol. Most of us are pretty happy with our fit. Bring your digital camera when you go for a fitting. A decent rule of thumb is your back angle..not slumped...should be about 45 degree with your hands on the hoods with slightly bent arms. You can almost do it visually or if more analytical...with some inexpensive photo editing software.
Purchasing a custom made frame for someone that isn't a freak in proportions whose intent is recreational cycling is a joke.
