I use to Mountain Bike when I was younger and I wanted to get back into it. After lots of thought I have decided on what bike I want to get. I am 6'3" and every website I look at says to go with a 21" frame. The bike I want is a 29er and comes in a 20" frame and a 22" frame. 20" frame says its for people 5'10" to 6'3" and the 22" frame says it's for people 6'3" to 6'7". I would go to the local dealer to try them out but they don't have them and need to order the bike. So theres the issue I am having. As far as I can tell the difference in the sizes are 1" standover height and 1" longer wheel base. I have heard getting the correct size will make a huge difference in my ride. PLEASE HELP!!!!! if you can. If not prayers are always welcome. Thanks a bunch in advance.
