A handheld gauge for cyclocross racing is a must. The gauge built into your floor pump simply isn't precise enough to use for the very low pressures you'll run on your cyclocross race tires.
This compact, digital PSI gauge is perfect for your toolbox or fits easily in your mechanic's back pocket. Features a quick release bleed valve, allowing you to over-inflate, then release small amounts of air to arrive exactly at the desired tire pressure.
I’ve had it for a week and it works awesome. In my opinion this is not a gauge to take on rides, but it’s ideal for your shop
