OK, so I've recently gotten into the sport, and after trashing my old NEXT (i know, i know... not even a real bike) I've decided it's time to invest a little bit of money. My primary concern right now is with size. I don't have an LBS that I can go to, the nearest shop is over an hour away, so I need to research as much as I can online, and I haven't been able to find any sort of info to tell me how to fit a bike. I've read that inseam for stand-over, and arm length for bars are important (obviously) but anyone have a better idea of what I need to look for? Really quick, I am 6'3" or 6'4" (depending on how much sleep I've gotten) with a 35"-36" inseam and a shoulder to tip arm length of about 31". Trying to decide if I should go with a 19" or a 21", but from the looks of it, that may depend on brand. Most companies are good enough to convert it for me, so I know what the actual stand-over and such is... Any help is awesome, and appreciated.
