Kind of but not quite true. If the popular wheel size is say 27” or a 700C that’s what goes on every size they make. Because an XS with 700C wheels is so much faster!
It's really not; I can go just as fast on my 26" as on my 700c (i.e. not very
), even though I'm more upright on the 26". Or do you mean it's all popular perception? Because that I believe. I was never much into fashion. (Okay, so there was that time in the '80s... never mind.
)
