Since I have been riding in the snow more and more on my fat bike I have to start paying attention to tire pressure. This usually is 6 in the front and 7 in the rear. Problem, no pump I had would read pressures that low.
The Accugage Low Pressure Gauge reads 0-30 PSI in a large easy to read display. It has a pressure release valve on the side as well.
The Accugage Low Pressure Gauge is about 2x as big as their regular tire gauge. Which makes reading the minute changes in pressure easy.
No complaints and completely affordable. I picked one up at my local bike shop for $15.
Accugage is made by the GH Meiser company who makes tons of gauges: http://www.ghmeiser.com.
