Critique continued - The big deal riding this bike centers on the ability to travel over rough pavement at speed without having to "stand". On any other frame, I would get off the seat in order to avoid the usual uncomfortable vibrations when encountering rough tarmac. This, I think, is based on the slightly curved seat tube which acts as a "spring" to absorb bumps that are normally transferred to one's butt when traveling at a fairly quick pace. I also found the Axiom's incredibly "soft" without the deadness of carbon yet exceedingly stiff when it's time to go fast and apply real power to the pedals. It's something that must be directly experienced in order to understand why this frame is such a revelation. At the end of my tour, I knew first hand that Seven's Axiom is truly state-of-the art technology that's built by people who have real passion for their craft.
