Does anyone has comment on the different performance between horizontal and sloping top tube frame? Thanks.

In theory compacts are stiffer in the rear triangle, but allow more flex in the seatpost. Most people, including Pantani himself agree that the main issue is cosmetic.

I think that they only look cool on a smaller frame, if you are over 6' they look a bit naff.
No difference in performanceKerry

Compact geometry: slightly lower frame weight, heavier seat post, a bit stiffer frame, more flex from the seat post. The reall difference is a bit more standover height and the chance that you can't put a large water bottle in the seat tube cage in the smaller frame sizes. Any other differences between two bikes are due to design choices in frame dimensions, tubing choices, etc. NOT due to the so-called "compact geometry" or "sloping top tube."
