We develop high-end wheelsets which enable you to regulate your tyre pressure while riding. Our wheels are fully compatible with existing gravel and mountain bikes.

We all know riding on gravel roads and mountainbike trails can be demanding. Because the surface of the trail changes throughout the ride it’s always a gamble which tyre pressure you need for the front and rear tyre when you go out for your 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, which is driven by the rotation of your wheels. Via an integrated clutch unit and electro-pneumatic control system the pump gets only active on demand. The wheels are fully compatible with standard bikes. You manage your tyre pressure wireless from your handlebars. Meanwhile, all relevant information can be displayed on your bike computer.

Inflate and deflate your tyres on the fly

Manage your tyre pressure

The uncompromising Gravaa wheelsets enable cyclists to adapt their tyre pressure on the fly. The hub in each wheel stores a miniature high-pressure pump, clutch unit and electro-pneumatic control system. The wheels are fully compatible with standard bikes and communicate wireless to bike computers via ANT+.

The wheelsets features:

  • Control your tyre pressure on the fly, once set the software will do the rest
  • Go faster by creating more traction or less rolling resistance on different surfaces
  • Improve your safety
  • Leave your bicycle pump at home
  • Get to know your tyre pressure: monitor the pressure in your tyres on your bike computer

Control your own tyre pressure gravaa

Get faster!

All the advantages listed:

  • Save weight; never the need to carry a heavy saddlebag or pump during your rides anymore!
  • Increase your grip by decreasing tyre pressure on soft surfaces
  • Lower your rolling resistance by increasing tyre pressure on harder surfaces
  • Never a flat tyre; even small leakages can be compensated by continuously adding air via our system
  • Superfast in- and deflation on the fly via a wireless control unit on your handlebars
  • Set the tyre pressure you want via the control unit and let the smart hubs do the rest
