Mountain Bike Help
I'm making a big push to get back into decent-to-good shape in 2013 and I'm going to try to get back into mountain biking/trail riding. I've been out of the loop for so long that I have no idea what I'm looking for in a solid bike. I'm not tall...5'9", so I need an 18"-19" frame. I'm also not wanting to spend a TON of money. If anyone is knowledgable about these things and would like to help out...please do. My budget is about $500-$700.
