This digital tyre pressure gauge is very precise. It measures pressure up to a maximum of 11 bar and is suitable for auto and sclaverand valves. The air pressure can also be measured with the classic bicycle valve, but only in combination with the Schwalbe valve insert.
Tip: Test the air pressure with a pressure gauge at least once a month. The well-known control with the thumbs is very unreliable. Even at only half the required air pressure, most tires still feel hard. Insufficient air pressure is very common with bicycle tyres. The result is a drastically higher rolling resistance and premature tyre wear.
