I'm a little stretched out on the frame, so may need to make a frame purchase/size based on that length. I have a straight TT on my Dawes (I think normal for vintage bikes). From about the center of the pedal spindle to the top of the saddle for me is 38.5". I think my LBS can do a fit for $150 although they said it can up to $300 depending on how much time they have to spend on it.
