Revolutionary cycling technology
When you choose GRAVAA, you choose better riding, more comfort, more control, more energy, higher speeds and fewer punctures.
All these advantages start with a unique technology: our tyre pressure system. Designed, developed and assembled in the Netherlands by a variety of Technical and Software Engineers. Read how this innovation works here.
We proudly present: KAPS!
The very first lightweight interchangeable tyre pressure system available on the market. Never before has anyone developed a technology that meets the above requirements. And we are proud of that. We call our technology KAPS, an abbreviation of kinetic air pressure system:
- Kinetic. This means: arising from movement. The pump inside is powered by the rotation of the wheels. It is you who drives the pump.
- Air. Perhaps the most important element that goes into the tyres.
- Pressure. The parameter that you control with this.
- System. An innovative collaboration of software, technology and components
High-performance, simple to use
To introduce you to this technology, let’s take you to the hub of the wheel. Because that’s where the lightweight system is located. Thanks to this innovation, you can inflate or deflate your tyre on the move. So you can adjust the tyre pressure on the fly to suit the terrain you’re riding on: from gravel roads to rough, unpaved terrain, from winding forest tracks to cobbled streets.
Operation is completely wireless. You regulate the tyre pressure yourself using two GRAVAA switches mounted on the handlebars. You can then check the pressure of the front and rear tyres on your bike computer (Garmin and Wahoo) or via the GRAVAA app on your smartphone
From riders, for riders
GRAVAA has been developing the KAPS-technology since 6 years. The past 2 years our engineers worked day in and day out to transform the Team Jumbo Visma ridden Paris-Roubaix 2023 prototypes to a consumer grade product. A product with better longevity, better usability and minimum service requirements. In short: a system to be used like we ride it outselves
The system now meets our high GRAVAA requirements, UCI regulations and those of World Tour riders. And include unlimited use; human-powered operation without an electric motor; lightweight; as small as possible; energy-efficient; easy to install plug-and-play system interchangeable with standard wheels. It worked!
Components of the Kinetic Air Pressure System:
- Mini pump. A small, energy-efficient pump powered by the rotating wheels.
- Smart clutch. You determine the desired tyre pressure. Has it been reached? Then the pump switches off to save energy.
- Fast air supply. Thanks to special valves, air flows quickly through small parts.
- Energy-efficient electronics. The pump is driven by human power. Energy-efficient electronics provide communication and control.
- Wireless connection. The system uses Bluetooth and ANT+ to communicate with your smartphone or bike computer (Garmin and Wahoo).
- Handy controls. A specially designed button on the handlebar controls airflow.
- Lightweight disc brake. Which makes room for the pump. Made by Galfer, leader in the brake industry.
