I have an Axiom Journey, and it works great. I bought it to solve two problems with my old rack. First, I had heel strike. The Journey is considerably longer behind the lower mounting points than my previous rack. Second, my old rack didn't want to fit above my new fenders. The Journey did so just fine.

I have the disc specific model. My bike doesn't have disc brakes (though the frame is disc capable), but it's what they had in stock and I wanted it that day. That RackTime AddIt looks nice. There is a Topeak rack that is also very popular here, though I can't remember the model (maybe more than one).
