|my fit kit measurement gave me an ideal bike size of 53.7cm seat tube
(c-c) However one of the bikes that I have test ridden and felt very comfy on is 54cm (c-t) of the seat tube. According to the fit kit this bike would be a little too small for me. But on a test ride I felt good. Is the spec on paper what I should be going by exactly or should I be using this as a " ballpark number" And am I wrong to assume a deficit of a couple centimeters if that can be made up by raising the seat post. the t-t length spec'd out well and like I mentioned I was comfy on the bike. Any insight on this would be great, Thanks

|seat post height, shoe/cleat/pedal stack height, seat tube angle and to a lesser extent crank length all have a bearing and can differ or alter your "ideal" seat tube length.
if the top tube, stem/bar reach and height is good then go for the 54 (c-t) and dont look back.
oh, was it a test ride or test spin? - the more miles the better idea on fit you will have.

|You should be using the "spec" on paper as a starting point, not a final target. It's easy enough to compound measurement errors when measuring body dimensions for fitting to come up with a centimeter of error. Plus, let's face it, off-the-rack bikes are like off-the-rack suits; most guys can wear a size or two up or down from their "true" size, and it depends on the maker. Finally, everyone's idea of what "fits" is just a little different, like with suits.
You also realize that the 54cm (c-t) frame you rode is only about one-third of an inch away from your fit-kit "ideal."

|I assume that your goal in submitting to the fit kit analysis was to find a frame that was comfortable for you.
You've found such a frame so you have accomplished your goal.
