Bike Pressure Gauges Are a Waste of Time and Money
I have a Spin Doctor (Performance) tire gauge. The ONLY problem and the MAJOR problem is when I test my tire I lose significant air when I depress the gauge onto my presta valve,
Is this common for all tire gauges because it really makes it a waste of time.. I pump my tire up to 110 using my pump gauge and then when I want to double check with the tire gauge I lose 5-10 pounds.
