Could anyone provide insight on the reasoning why some manufacturers make top tubes that rise while others drop?
Example- Ridley Dean vs. Specialized Transition (or Look 596)
With all other geometries the same, the Dean allows for a shorter seatpost while the Transition has to have a much longer post to have the same drop. Aerodynamics are impacted, as well as frame flex’s, I’d assume. It’s just something that crossed my mind while looking at pics of the ToC today.
it’s probably just fashion.
the longer post is advantageous because the UCI regulations don’t limit the aspect ratio of the seatpost so you can make it very thin and deep. Ridley simply chose not to take advantage of this.

is it possible that ridley was worried about whether or not they could make their seat mast stiff enough if it was really, really long?
i’m not an engineer, so that’s a real question to whomever is capable of answering.
