Asking a bunch of questions when you are new is a very good idea. What I take issue with is that you open a new thread for each new question. Makes it difficult to follow your thought process. I have had to look at multiple threads to try and figure out where you are going. Honestly, my head is spinning trying to follow your timeline. Is this question newer than the last question you asked? Was it older? You seem to be fixated on the idea of racing in the future. Don't look at road bikes with 10 speed cassettes unless you want neutral support cars that only have 11 speed wheels to be unable to help you. Doesn't matter if the bike you look at is a dedicated race bike, many races have been won on good bikes that were designed for less competitive events. A bike designed for criterium racing would fare badly at Paris Roubaix. For a newcomer, a bike designed for Cyclosportifs,(Gran Fondos) is an excellent beginner's race bike. These are the sort of bikes pros use for races like the cobbled classics.
