Handle Bar Horizontal/Handle Bar Vertical
I recently sprung for a pro fitting from a reputable shop in New York. The guy was knowledgeable, helpful, informative-- a real pro. A week later he emailed a draft of measurements for a custom fit, along with a fit diagram. He also made drafts for a few stock bikes, ie, how to make a Cannondale Synapse get close to the custom fit.
My question has to do with the measurements for the Handle Bar Horizontal Distance and the Handle Bar Vertical Distance (measured from the Bottom Bracket).
On the fit diagram these measurements are: 41.7 cm and 66.2 cm.
On the custom draft they are: 41.2 and 66.8.
When I called to ask about the difference he said that when drafting a custom bike he can use any size tube, and therefore the target measurements are factored differently than on the fit diagram, which is used to fit a stock bike, in which the tube size is always the same. That makes some sense to me. But on the couple drafts he wrote up for stock bikes, he used the Horizontal/Vertical target measurements from the custom draft, not the fit diagram.
I'm a bit confused. This is my first pro fitting, and I'm probably going to spring for a custom frame. But I want to make sure I'm doing this right. The fitter seemed like a stand up guy, so I want to give him the benefit of the doubt. But something doesn't feel quite right. Could this be a problem of a pro jotting down the wrong numbers during a busy week? 7's looking like 2's and 2's looking like 8's after a few too many cups of coffee?
Thanks a bunch for any advice.
