Hey all. This topic has probably been hammered to near lifelessness, but I'd like some perspective as it relates to my intended application. I'm building a TT bike and will be looking at new wheels. I typically ride 28's on my road bikes. But for going as fast as I can in a straight line, will 25's be superior? If so, why?

Also, can I get recommendations for a fast tubeless tire?

Also, can I borrow $25 for a McRib sandwich to sustain my training? Thanks!
