I have ridden frames with 25 inch seat tubes before. There is no clearance between my privates, but I find that taller frames and long headtubes make for a more comfy ride.

Right now I'm on a 60CM...But could probably score a 63CM bike with a Chorus groupo for a good price. The top tube is 59CM...The last frame I road with a 23 inch top tube felt radically more comfortable than a 22 inch top tube.

For those wondering...The bike is somewhat out of my price range but its 1100$ for a Waterford with Phil Hubs and a Campy Chorus group. That seems to be something to consider. Provided I can make it fit.

Top tube will be on my privates...But a fist full of seapost will likely be used. I'm running over a fist full on a 60CM frame. Oddly enough I'm only slightly over six feet. Long upper and lower body.

For me bigger has always been comfy but this might borderline too big. What are your thoughts on the classic fist full of post formula and big frames?
