A friend is building a CX bike for me. I'm debating between getting a wheelset for clinchers or tubulars. (I assume that you can't put clinchers on a wheelset and then use the same wheels for tubulars.) As a rookie should I step up and start out with tubulars? As a rookie would I be able to take advantage of tubulars, or will I be such a noob that I could be using wooden wheels with iron tires and wouldn't notice the difference?
