JACO Superior Products FTX-30 Low Pressure Presta Tire Gauge for Bikes (Max 30 PSI) | Fatbike & MTB Series

The large dial covers 0-30 lbs in 1 lbs increments. On my mountain bikes, where I usually have around 20 lbs, and my fat tire bike, which I usually have less than 10 lbs, this gauge is so much easier and precise that the gauge (0-120 lbs in 5 lbs increments) on my pump. The carry case is study and protects the gauge as it bounces around in the back of my truck.

I use this for my snow bike - where I keep the tires from 5-8 psi depending on snow conditions. My pump gauge doesn't even register below 12 psi, whereas the precision and accuracy of the JACO makes the difference between 5-8 feel huge. I like the ridged exterior. It might look like a gimmick but is really useful with cold fingers or wearing gloves. The bleeder valve button is also a critical feature, making it easy and convenient to over-pump a bit and then bleed down to the desired pressure. It's also convenient that the range goes up to 30 psi since I ride with higher pressures in the non-snow seasons. The case also turned out to be handy since this tends to travel in the xtra cab of my truck tossed in with other gear.

Purchased for MTB tires and fatbike tires for pressures of 3 psi to 25 psi. I tested the gauge the day I received the package last week, and it is reading about 50% of actual. Also the gauge is supposed to hold the reading until pressure is released, but my unit looses pressure as soon as the gauge is removed from the valve.Jaco sent me another gauge in two days. Unfortunately both gauges do not hold the pressure reading. One the plus side, the presta chuck is really solid, and the new gauge gives accurate readings on my fat bike tires which I ride at 3 - 8 psi.

I bought this to keep track of my tire pressure, getting used to tubeless tires. Easy to use, and I love the button to bleed off air.

I ride a plus tire hardtail on some pretty gnarly stuff and tire pressure is very very important.Seemed well made and worked well... then 3rd use it stopped returning to zero and every reading wildly changed.Could be just mine but I'm curious if they hold up long term typically if it went out that fast.
