AZUNO Bike Tire Inflator with Pressure Gauge - Bicycle Presta and Schrader Air Compressor Tool

I've seen reviews that say it doesn't work on Presta valves, but I have had no issues with either type. It has worked well and seems accurate. I was able to seat a new 27.5x2.5 tubeless mtb tire easily. I'll post again if I run into any issues, but so far - so good!

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!

I didled btw 4 or 5 stars, but I like reading 4 star reviews more and this wasn't perfect even at this price. It took all of my strength to remove the air fitting and change to match my air hoses, but it was handy that the teflon tape was provided. I like that the dial is back lit and appreciated that it came with batteries. Not sure why it's necessary to add an additional hose to convert to presta, but it is. Not saying that's bad, but it makes for a longer hose than I like. Ergonomically, it fits nicely in an adult hand and the lever feels solid. Overall, this feels solid and not sloppy and the price was very reasonable. Only wish you didn't need to clamp the end of the presta hose to fill the tire when just holding on the valve stem would be so easy.

This thing is amazing. Dual haed Presta Schrader nozzle is so much easier and more efficient than my bike pump, and the whole set semms high quality. Gauge is accurate enough, accessories are thoughtful.The locking feature on the nozzle is the best I ever used, great quality. You put the nozzle into your tire's valve, and then you flip a switch and it locks in place perfectly. On my old bike pump, you'd hear a hissing noise so air would escape and you'd have to fiddle with it before it stopped, and even then it'd still hiss a bit. No air leaks at all from this nozzle. The pipe lenght is very generous, 40'' not including the nozzle.I like the digital PSI gauge, large number and bright LCD, much better than my old dial gauge. The chuck simply clips straight on to the valve stem with almost no loss of air, and the pressure reads out on the gauge automatically. Then just press the lever on the gauge until the pressure is correct. If you go slightly over, use the pressure release button on the side to let some air out. When the pressure is right, release the valve stem and remove it quickly.Great set. Worth the money.

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.

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.

There is no presta attachment I wish I would have read the one star reviews I usually do. 😤But right in the title it said it had it so I didn't double guess.But as you can see there's clearly a brass piece to push down on the Schrader valve so presta will not fit in here no way no how.
