The bottom bracket on my old conversion is pretty much dead and i thought that a new bike would be a great idea. I have currently narrowed down my choices to the Mercier Kilo TT, but the problem is, is that I'm not really sure what size to purchase. I am approximately 5'9 and a quarter and I have a stand over height of 31.6 inches. I am guessing maybe a 50 or 53... thoughts?
