Accu-Gage Fat Bike Presta Valve Low Pressure Bicycle Tire Gauge, 15psi

Bought as a replacement for a gauge that finally went belly up after years of use. The new gauge has a larger dial so is much easier to read. It also holds the last reading until the release button is pushed. In addition it seems to be very accurate when checked against a couple other gauges. (Only one minor concern re the packaging: when first opened, it appeared the gauge was for automotive use & there was no indication it’s made for bicycles. However, it is indeed designed to fit bicycle presta type valves so no worries. The manufacturer may want to update the packaging to reflect this).

The gauge works very well and most importantly it cleanly seals to the presta stem. There is very little air loss when engaging and disengaging the gauge to the stem. This is important to me since a slight air loss can make a significant difference in resulting tire pressure of tiny road bike tires. The gauge also holds the pressure until you press the button to reset the gauge, and therefore you can also bleed-off excess pressure with the button..The gauge is a bit bulky in size. I mention this simply for those who intend to carry the gauge in a seat bag under the bike seat. In a small bag, this gauge occupies a good bit of space. But I can still fit my plastic spoons and spare innertube within my seat bag, which is quite small.Very pleased with my purchase. I have an old Accu-Gage schrader style 0-60 psi pressure gauge I inherited from my father's tool collection maybe 30 years ago. I've used that gauge for auto tires for many years. That gauge continues to work accurately to this day. Maybe 20 years ago I bought a replacement Accu-Gage 0-60 psi schrader style gauge, thinking the old gauge would eventually crap out. Nope. Keeps on working. So I was pleased to see Accu-Gage offers a presta style gauge and I was compelled to buy it based on how well their gauges have performed for me over the years. I guess i'm getting old if I can actually make those statements!

works as expected - this was to replace my old one I clogged with tire sealant(by accident).

Consistent and accurate. Liked the easy to read gauge and that the needle stays in place after removal to easily read what the pressure was. It’s bit larger than I’d like. And the rubber fitting on the outside seems like it is a bit loose and should have been glued to the gauge. Overall I’m pretty happy with it.

Used for checking bike tire (with presta valves) pressure, Although not as easy to read as a digital gauge, even my aging eyes have no problem reading the Accu-gage. It has a large face, appears very durable (metal encased in a rubber housing), and was easy to get on and off the tire valve with little to no loss of air pressure. I have faith that its readings are accurate, as they match the readings from my Silka pump gauge. It is a bit heavy, but that's probably a trade off because the durability factor.

This 160PSI pressure gauge is pretty nice. It has a right amount of heft to it and it feels solid. If truly a ANSI b40.1 then it is 3/2/3 +/- %. I use it for my road bike so normally in the 100+ psi range so this gives me a +/- 3% accuracy and I am happy with that.I found that if I push the gauge nozzle directly inline (no angles) into the presta valve there is zero air leakage. If you misalign the nozzle when inserting into the presta valve then some air will leak before the gauge seals it prior to displaying the reading.The air relieve valve also works quite well. When relieving air by pushing the bleeder button I immediately exit the presta valve and then re-insert the gauge to double check and more times than not it shows the same air pressure pretty much.I also own a digital Topeak guague and because it is a smart valve I still have not master the valve insertion without some amount of air leakage. The Accu-Gauge sovled this problem.

This gauge stopped working after 1 month. It won't go back to zero after I release the air. It stays at 4 psi and then the readings it gives are incorrect.

Large face makes reading the gage quite easy. Running tubeless on a road bike and tire pressure is very important. Slips over the presta valve easily, hardly any air loss, holds the reading until the release button is pressed. Over pressure can be released by pushing the button. I'm a couple of months in, so long term reliability is still a question.
