It is really a simple and complete truth that many would choose to deny. The truth is, nothing is constant but everything is constantly changing. All things that appear permanent are actually always converting. That is why the only true permanence is conversion. This concept has been embraced by the Jetpilot team and they have translated it into many aspects of our company. From their product line down to the details of how they ride. It is basically progression. Replacing the past with the present and what is now. Changing the mentality of those who believe that constant means "same" or that it is a truth to comfortably grasp. Jetpilot is continually on a path of conversion, a path of progression, a path that embraces change, a path that seeks new ways to innovate our products and better our riding experiences.
