50 cm is the smallest "Vaya" there is - with a 698.1 millimeter standover puts it at a 27.48 inch. 52 cm is 715.3 or 28.16 inches. Also, discs brakes and STI shifters. I'm not a fan. Also, it is a "compact double" no bail-out low gears (granny gears) if you hit steep hills. 50/34 T rings are bigger than the LHT stock rings - meaning harder to pedal for beginners - good for speed not for touring. LHT has 26 inch tires. Nice wide good for multi-surface. If you like the look - brown paint/brown saddle/browntape - the Trek 520 is a stellar bike that costs alot less (than a Salsa) and comes in a rich brown with golden flecks in the paint. It's not a Surly but it is a nice bike - that has been manufactured for over 20 years.
