Tire pressure makes the difference

I've been riding for decades and usually just use the squeeze test for checking tire pressure. I bought this tire gauge. Super-easy to use and found out that I've been under-inflating my road and mtb tires by a lot. My road tires have had around 42 PSI (tubeless, 700x32) and now I have them at 65 PSI still below the 75 max and the bike is now gliding. My MTB tires were around 35 PSI and now riding around 45 - I'm able to go around turns faster with more control. I was reading an article about tire pressure recently and this had made a huge difference in my riding.

Good Overall

Familiarity:
I've used it several times

Picked up this gauge for gravel riding as I like to adjust pressures based on riding conditions. Easy enough to use, although there were a couple times the unit did not read pressure, but a quick reset fixed the issue. The unit is pretty light, wish the shape was more friendly for jersey pockets or top tube bag.

Good gauge

Familiarity:

I've had this gauge about a month now and I like it! It is well designed, easy to use and based on comparisons with other gauges that I know to be accurate, this one is accurate from trail bike pressures through gravel bike pressures up to road bike pressures.

works fine, might as well get the blackburn one with a lifetime warranty.

Tested this against some other gauges before starting to use it as my only gauge, and its very accurate and easy to use.

Best pressure gauge out there. I use it for my bikes, dirt bikes and my car. I highly recommended.

Sweet!

This little thing is great and very accurate. I use it for my bikes and my vehicle, and It's been very handy!

Always check your pressure

It's amazing what difference a few PSI makes, get it dialed every ride.

Works Well

This gauge works relatively well. I keep it in my tool kit in the back of my truck to check pressure pre-ride. Adds confidence to your pressure choices.

Great to have on hand

This is so much more accurate than the standard air gauge

It works. It shows you the PSI in your bike tires. It seems to be consistent with the PSI. There you go.

Best One I've Used and Abused

Familiarity:
I've put it through the wringer

Dead easy to use, accurate in typical road, mtb, 'cross pressure ranges. Good battery life, easy to read, works equally well on presta or schrader. I've got one I've been using for 5 years, battery typically goes at least a year and I check pressure almost daily. I had a second one I kept in my ride kit in my jersey that I dropped and broke the yellow selector tab on but that was a freak accident, replaced it with a new one straight away. Best one I've seen or used, highly recommended.

Great little gauge for regularly checking air pressure. Works with different valve types and makes adjusting pressure easy.

Nothing super fancy, it does what it should. Good value.

Easy to use

Familiarity:

Works better than several alternatives I tried (they all released a ton of air from schrader valves while trying to get a good fit). The instructions were not helpful but there are only so many buttons so it only took a couple of tries to get it down. One thing the instructions dont explain is the

Does what it is supposed to

Familiarity:
I've used it once or twice and have initial impressions

Very easy to change between valve types and units of pressure to suit personal needs.Fits in the hand nicely. Head will swivel to allow access to different valve angles so you can see the readout but this feature presents some instability and will sometimes allow the head to flip off the valve. Recommended.

gauge is great and accurate.

A great gizmo for any rider who travels. A great way to keep track of tire pressures. If you race, you need this. It it superior to its competition and can be used for a wide range of pressures.

Works great after initial problems

Familiarity:
I've used it several times

This is an expensive gauge so I was expecting a lot. At first, I was disappointed. I was getting poor engagement with the valve, sporadic readings or no reading at all and losing lots of air from my MTB tires. I was about to return it but reread the instructions first -- "If it's difficult to engage the tire valve, slide the Presta/Schrader selector button back from side to side a few times to reset the function. 'Re-engage' the tire valve after gauge is reset." Presto! Problem solved. The gauge has worked great ever since and I can get exactly the pressure I want, very important for my MTB as I ride as low a pressure as I think I can get away with.

>Rating:

What is the accuracy of this gauge and what is the lower limit of pressures it will read with accuracy? Looking for something that will work on fat bike tires down to 4psi. thanks

It's quite accurate but for fat bike tires you are going to need a gauge designed for those pressures. It will read in the 4 psi range but I have my doubts about accuracy at that level.

Will this work with unthreaded CO2 cartridges? The kind you can buy in bulk for cheap.

Sorry, but I don't understand the question? Do you want to check the pressure on the CO₂ cartridge?
