...and if you score a good conditioned beast you can keep the spec when you outgrow the frame and move onto a bigger frameThe 5'6" or so size is in the cusp zone for many manufacturers between small and medium. I am 5'7" and riding a small Intense. So rider preference is a big factor too. I had a riding mate about 5'9" rode a large Kona, even though within the medium standard range.
I like a small bike as it feels easier to toss around and be more responsive.
