So basically, yes. I have been advised against buying a 56cm bike in the past, although I don't know if the same rules apply to mixtes... However that bike doesnt have drop handlebars. I am pretty much just trying to be a little bit more flexible so I can hope to come across more in the future. I also don't want a bike that won't fit as I want to ride it!
