What makes the Jet 9 so good, and so much better than its predecessor? It is all interrelated. The new wheel is more aero, it has lower rolling resistance, it corners and handles better, and it more comfortable – all increase speed, and all are a result of our C2 rim technology. The C2 rim is 23mm wide; and that fact alone does not make it revolutionary, and by itself a 23mm rim width is not “technology”. What we did with a 23mm rim width, and what it allows for aerodynamics, rolling resistance, and bike handling are what make the C2, and the new Jet wheels revolutionary.
