Ben, Hi, interested in the fortitude ss, I have the option to get one -unseen - 2012 model. medium frame, but I can not find any geo. or spec to compare. I am 5'11" , any idea if the medium would be too small (top tube length really) thanks. And how do you like it??

 The Large is perfect for me and im 5'11", good geo with slack front end (cant run a suspension fork though/recommended by manufacturer).

As
