I am a 5'3" guy and am probably going to get the 47cm mercier kilo tt. I assume that the 50cm would be too big. I have a 28" inseam, so I think the 47 is the right size. Anyone think a 50cm would be better for me? I have a 44cm motobecane road bike and the standover is good, but i feel like the reach to the handlebars is kind of close.
Also, my 44cm Motobecane Road bike came with 650c tires. So with a 47cm frame size (or even 50cm), does that mean I should have 650c size tires? What about any other components that would have to be non-standard size with a smaller frame?
