Review on 🚲 CycloSpirit Universal Bicycle Tire Inflator Gauge: Auto-Select Valve Type - Presta and Schrader Air Compressor Tool by Christian Byrd

I have found that when using this valve on a bike the Presta valves require a lot of pressure to seat and remove which causes some air to leak out get lost. Also because the Presta valve has to be inserted so tightly that pulling it out can hurt fingers etc. This is a compromise with the Presta valve sealing rubber: if you soften it, it wears out quickly. It works, but my bike pump has a much better mount for Presta valves. This works perfectly with Schrader valves. An analog gauge is within 1 or 2 psi, but is much easier to fill and depressurize than a digital gauge due to the poor hysteresis of some digital gauges. When you need the best pressure measurement accuracy, a properly calibrated digital pressure gauge will be more accurate than this analog pressure gauge.
