SCHWALBE Airmax Pro Air Pressure Gauge blue

The digital air pressure gauge is very precise. It measures pressures up to a maximum of 11 bar and is suitable for car and sclaver valves. The air pressure measurement also works with the classic bicycle valve, but only in conjunction with the Schwalbe valve insert.

Note
Check the tyre pressure at least once a month with a pressure gauge. The widely used thumb pressure check is very unreliable. Most tyres feel tight at half the required pressure. Insufficient air pressure is widespread on bicycles. The result is drastically increased rolling resistance and severe, premature wear of the tyres.
