I have a Kona Jake the Snake cyclocross bike. I bought it thinking I would ride on gravel and dirt with it (I'm mainly a mountain biker), and after a few rides even on a rail trail, I gave up that idea because my back, arms, and hands ached so badly from such a stiff ride. I love the bike and really enjoy riding it on the road with road tires. I don't regret buying it, but kind of wish someone had clued me in as to what a harsh ride not having any suspension can be!
