The revolution is here
A gravel bike leads you to places on and off the paved roads. Because the surface of the trail changes throughout the ride it’s always a compromise (or gamble) which tyre pressure you need for the front and rear tyre when you go out for your gravel ride. In the end you often settle for the middle ground regarding tyre pressure. After years of research and engineering we have developed high-end wheelsets which enable you to manage your tyre pressure during your ride.
The lightweight wheels compose of carbon rims and advanced hubs, in which a miniature high-pressure pump is stored. This pump is driven by the rotation of your wheels: by you. Via an integrated clutch unit and electro-pneumatic wireless control system the pump gets only active on demand. The wheels are fully compatible with standard bikes with disc brakes. You manage your tyre pressure wireless from your handlebars. Meanwhile, all relevant information can be displayed on your bike computer or smartphone.
