I am considering a purchase of a new mtb. One of the bikes I have in mind is Rocky Mountain Vertex 70. In the past I've heard good things about this Canadian bike manufacturer but I've never had any experience with their bikes. Therefore, I would like to hear from you if you have any experience with Rocky Mountain bikes, their build quality, set-ups, ride quality and so on. your opinions do not have to be limited to Vertex 70; other RM models are fine as well. I am just trying to get a better feel about Rocky Mountain.
