Schwalbe Airmax Pro Pressure Gauge

The digital pressure gauge is very precise, measuring pressures up to 11 bar and is suitable for Presta valves. Schwalbe claim it will also function with Schrader valves though in practice we havn’t found it a very good fit on them.

Tip: Test tyre pressures at least once per month with a pressure gauge. Testing by thumb is completely unreliable as with just half of the required pressure the tyre will feel hard. Insufficient air pressure is the most common bicycle problem that results in dramatically increased rolling resistance and premature tyre wear.
