Schwalbe Airmax Pro Tyre Air Pressure Gauge
Most people choose their tyre pressure based on feeling or the pressure gauge of their standard air pump. If somebody measures the precise air pressure he will recognise, how his feeling varries, respectively how inaccurate his air pump gauge works!
The correct air pressure decides not infrequently about slipping or not.
With this gauge you can measure your air pressure exactly to 0,1 psi and one-time measured values can be easily restored any time.
-Works with schrader and scalverand valves
