SCHWALBE gauge AIRMAX PRO
High precision digital manometer. Fits Presta and Schrader valves and pressures up to 11 bar.
It is recommended to check the tire pressure at least once per month with a digital gauge. A check tire pressure with the thumb is insufficient because only half inflated tire already seems to be properly inflated.
It is common for cyclists ride with under-inflated tires. They thus run the risk of reducing adhesion. In addition, tire damage faster.
