- Comfort: With the valve bent to 45 degrees, you can inflate the wheel with any pump in the house. Forget about the problem of torn off chamber fitting. The optimal air pressure for the wheel is between 1.2 and 1.5 bar.
- Safety, for all seasons. The hose material is lead-free and can also be stored near food in the home. The tube is very wear-resistant and can be used safely in any season and in all weather conditions.
- Replacement method: Inflate the pipe easily. Insert the tube into the tyre and distribute it evenly throughout the tyre. Install the valve fitting into the wheel.
