AZUNO Digital Bicycle Tire Inflator Gauge, Auto-Select Presta & Schrader

Updated Review December 2020: After my initial review, which you can read below, I was contacted by Azuno via email. They wanted to make it right in two ways. First they were taking details from my review to help make the product better, which is how it should be, so I appreciate that. Second, they offered to refund my purchase or send me a newer product to better fill my needs. (There was a third option, but I can't remember it at the moment.) I took the newer product. I like to see a company take accountability for a bad product and then take steps to make it better. Original Review October 2020 was two stars: Got this Azuno bike tire inflator to inflate my road bicycle tires. First time I used it, it worked fine although it does leak, but it wasn’t so bad that I couldn’t accomplish what I needed to do. Temp went down to the 40s so I figured I should check all vehicle tires. Did okay on both cars, but it did leak more than the first time. Both vehicles are at 33 psi, so not too high. My bicycle though, is 100 to 130 psi and I usually go 115 psi. I got it on the presto valve., which is always way more difficult than it should be. Squeezed the lever to get the air to flow and the hose on the presto adapter split. I took the that assembly apart and cut the split section off then reassembled it. Stuck it back on the valve and pulled the lever and “pop” it went again. It’s also very difficult to remove. The garage works good though, but it does leak a little which I figure it will inevitably get worse. I should’ve known better since the description is very poorly written, but then again so are a lot of the reviews, LOL!

Works well

Not good for presta road bike tires that need 120 psi or more. The presta hose pops. I removed the pop hose and glued it and haven't tried it again since. I see other reviews say the presta valve really doesn't work. I realize now I damaged and destroyed a tube trying to get the presta valve to stay on. Infuriating. I did fix the broken hose with shoe glue (pic) but I see from other reviews that presta valve probably still will not work. The entire reason I bought this one was the included presta valve. update: after removing the extended presta hose that popped I am able to get my bike to 100psi (and maybe more?) without too much headache. Seller has been easy to work with so increasing rating to 4

I am able to use this on my bicycle and motor vehicles, except my motorcycle. Beats switching back and forth between an air gauge, air chuck and manual bleeding of air from the tires. Seems well put together; solid, not flimsy. Guage is very easy to read. As others have noted, can be a little tricky to fit over a presta valve, but a good push and it locks tight over the valve, although it might take two or three attempts. Cannot maneuver the hose on the tire valve of motorcycle due to tight space of valve behind the wheel spokes, hence four stars foe "ease of use," however, perhaps a horizontal valve would solve that problem. Will install such valves at next tire change and see how it works. Overall, very pleased with the product. A good value IMHO.

I review only Excellent or Very Bad products. Unfortunately, this falls into the latter group ... IF using it for PRESTA valves (which I purchased it for), found on most all performance oriented, quality bicycles. As background, I have 56 years of bicycle maintenance experience with my own stable of bikes over the years. I have also attended professional training classes on all aspects of bike maintenance, and I have 10+ years of experience working in bike shops. Recognizing what a good tool is and knowing how to use them, this one fails even the 'good enough to get the job done' test. As others have commented, the Presta adapter ... consisting of a 10 inch length of rubber hose with a 1/4" NPT fitting on one end and a plastic Presta valve connector on the other ... is unworkable because it leaks constantly due to poor design. There is no 'user fix' to correct this, except to remove the plastic Presta valve connector and replace it with one that works. I own three good foot pumps, each with a plastic or metal+plastic Presta valve connector that work flawlessly and without leakage. I do NOT want to, and should not have to, cut off one of those and replace the poorly designed Presta valve connector on this AZUNO compressor-air powered gauge and inflator. So I am returning it. Though it worked well with the (included) Schraeder Valve connector and provided accurate PSI readings (I compared its reading with a couple of known-quality pressure testers), SAVE YOURSELF TIME AND TROUBLE and look elsewhere if you want a unit that will reliably inflate PRESTA VALVES and display an accurate pressure reading! This tool WILL NOT do that.

I have started to maintain my own bicycle lately. This included swapping road and gravel tires are couple times a year. I had need of a presta based tool to work with my pancake air compressor. I saw this kit, and it seems like it would do the trick at a reasonable cost. Honestly, I found it a little difficult to work with. The nozzle did not fit as securely as I would have expected. The pressure reading on the digital display was surprisingly slow to update. In hindsight, maybe an analog dial would have been better. This kit has all you would need, fittings an all. However, I'm just disappointed in the gauge and the nozzle itself. Because of this, I would not recommend to others. Would I recommend to others: No Would I purchase this again: No

Wow this thing works better than advertised. It fills up your Presta valves bike tires with ease. Not only that I used took off the Bike hose attachement and used the brass schrader valve attachment. The brass fitting attaches to Schrader valve stems without leaking. It has a squeeze trigger that locks onto the schrader valve to hold it in place. I used the brass schrader valve attachement to fill up the car tires on the wife's Rogue. I love how it shows the psi as you leg go of the trigger and has a relief valve to let air out if you over inflate the tire. This bad boy is just like what the professional tire shops use.

Got this inflator attachment for seating tubeless tires on my gravel bike. I saw a few questions saying this product didn’t have enough pressure to seat tubeless tire beads, but mine worked right away after setting my compressor to about 100psi. Both 700c wheels set up quickly with 38c tires and I was easily able to dial pressure with this tool’s bleed valve. Great tool so far, can’t comment on durability or longevity, but it served its use right out of the box.

Tres bon

Works good on all my bikes except the road bike. Though it says it's good for 100psi the nozzle seems to start leaking around then. If your desired pressure is below that, should be good enough.
