Wabisabi, if you do this go through a fitting process on some kind of fit bike. They eventually did what Joe and Bill said but the intitial set of numbers were for a very long and low cockpit for a 20 year old racer boy (not my sexy but ain't getting younger 57 yr old). Apparently, they do this for just about every bike. Joe would set up the fit bike on their numbers and then tweak it to the position Bill wanted. The geometry really worked.
