Review: Absolute Accuracy and Zero Frustration - When my Toppeak analog gauge finally fell apart after over ten years of heavy use my first thought was to get one exactly like it, but I was attracted to the feature on this gauge which allows you to release tire pressure while reading it as it drops and the fact that it has a single hole head which is compatible with both Presta and Schraeder. Months later, I couldn't be more pleased with this gauge. When I look at the gauge on my Lezyne Alloy Floor Drive Pump as I'm pumping up the tires the gauge on the pump is fairly accurate, but you can't increase pressure by only a pound or three, and you can't decrease pressure with it at all. So when I overpumped the tire--as on most any floor pump--I would have to remove the pump from the valve, take a wild guess about how much air I should let out, and repeatedly use my old analog gauge to check it until it was roughly the pressure I wanted. With this gauge I always put more pressure than I need in the tire, then remove the pump, measure the pressure--which is too high at that point--then press the button to measure the pressure as I use the release button to get it where I want it. This would be a pain in the butt if it weren't for the swivel head on the gauge which allows me to point the display where I can easily see it rather than change the position of the tire or tilt my head to view it. Overall this process has become quicker, easier, and more accurate due to this gauge. And it's a great benefit to other riders when I'm on a club ride or volunteering as a ride marshal in a community bicycle tour that with the flip of a switch I can change between Presta and Schraeder valves without having to take it apart or switch around any gaskets. A lot of people will tell you that you don't need a gauge, that they can tell just by squeezing the tire. That's nonsense. I used to think that until I finally bought a gauge and found out that when my mountain bike tires feel rock hard by the squeeze test they actually have only about 25 psi in them when they should be at least 50 psi, and my road bike tires might feel rock hard at 60 psi when they should be 120 psi. For reference, your car tires only take about 35 psi. And by the way, this is a great gauge to use on your car too. I check the tire pressure on my car at least every month, and more often when the seasons are changing. Sometimes I need to put more air in using the electric pump on my Slime 50051 Safety Spair All-In-One 36 Piece Roadside Emergency Essential Kit and sometimes I need to let out a pound or two of pressure. With this gauge, I don't have to guess how much air to let out when the pressure is too high, checking each tire multiple times until I have it right, or use the needle on the analog gauge to get an approximate pressure reading. Whether on my bikes or in my car, inaccurate tire pressure can mean compromising fuel/power efficiency or traction, and with gas prices what they are these days even another three miles per gallon matters in my car, and incorrect pressure in bicycle tires make for a harder ride and lower endurance. So instead of thinking that maybe this is a little over the top, I recommend you buy it. The price is certainly reasonable and I doubt you will regret it.
Review: Portable tire gauge - Life saver to have when out riding! Accurate and easy to use. Swivel feature is good making it easier to read. Pressure release button is also a great feature when tires are over inflated. I’d definitely recommend.

## Questions & Answers

**Q: Will this work on Presta and Shrader valves?**
A: Yes. The yellow slider on top has both Shrader and Presta positions. It's easy to slip on and off without losing a significant amount of air, and the readout is very visible. The head swivels to make the gauge fit comfortably in your hand no matter what the angle of the valve. I've had this gauge for a year and definitely recommend.

**Q: How does the air release reading work on this?!  i press the release button and air is escaping but the psi doesn't lower on the readout.**
A: You have to be in the correct mode for this.  After first reading the pressure, press the button with the circle on it labeled "tune" then use the yellow air release button to let out air and the unit will automatically read the new pressure.

**Q: Does this work correctly with presta valves? i know the description says so, but other gauges also claim that and do not perform well with them**
A: Yes, it works with presta valves.  There is a setting for presta and a setting for  schrader.  Testing on a presta requires you to quickly get the guage on the valve.You must also remove the gauge quickly. It would be nice to have a presta guage that worked as easily as the guages do on the scrader valves, but I haven't found one.  This guage works fine on both types of valves

**Q: Does this gauge read low enough for Fat bikes 4-7 psi?**
A: It does read in the single digits but no decimals. So, if you're looking to fine tune to 1/2 or 1/4 psi increments, it isn't that precise. The Accu-Gage analog units can do that. However, I have one the goes to 15 psi max and reads in 1/4 psi increments and one that goes to 30 psi max, 1/2 psi increments and they read 1 full psi apart from each other. So, perhaps the fractional readings are pointless.

### ⭐⭐⭐⭐⭐ Portable tire gauge

Life saver to have when out riding! Accurate and easy to use. Swivel feature is good making it easier to read. Pressure release button is also a great feature when tires are over inflated. I’d definitely recommend.

### ⭐⭐⭐⭐⭐ Nice gauge
*by C***R on November 23, 2013*

This gauge is a beaut. I bought the previous version several years ago, but was never really happy with that one. This new model has picked up several improvements and is a lot better. It's now easier to use, and most importantly it takes fast and accurate road bike tyre pressure reading with virtually zero air loss. If you're like me, you can probably estimate the air pressure in a high volume MTB tyre, but that's less critical anyway and the pump is usually enough of a guide for such tyres. However, with high pressure road tyres, knowing the difference between say 70psi and 110psi is less obvious from just squeezing the tyres with your fingers or putting your weight on the bike. Making it worse is the fact that most floor pumps don't have particularly accurate gauges on them, and more importantly... low volume high pressure tyres can very quickly change pressure from even a momentary air loss! The body of this new version rotates, making it simple to take readings without any mucking about or getting down to the wheel level eg. when valve is at the top, just have the gauge display facing up, simple. The gauge now fits better in the hand, and the ON button is easier to use. It takes a single CR2032 battery which fits with less nonsense than before. There is also an added air bleed button and a continuous reading mode, to allow readings while releasing air (with the gauge still attached). I always stick with PSI readings, but bar readings are also available (plus kilograms per square centimetre if anyone wants that). The smart head works well with both Presta and Schrader valves, allowing it to double as a shock or fork pressure gauge. I should mention though, that this is primarily a high pressure reading gauge (max 250 psi) and road tyre pressure readings with Presta valves are quick and leak free. Low pressure in a Presta valve tube will cause a temporary air seal leak when connecting or disconnecting the gauge... but this is NOT a fault, and it will not upset the pressure in MTB tyres unless you have no idea how to use it properly. It's the air pressure behind a Presta valve which seals it and facilitates the nice sealing around this gauge (Schrader valves depend on a spring inside the valve stem, but usually work with lower pressures eg. wheel barrow, car tyre). A sliding lever must be moved to accommodate Schrader valves, which also work just fine. Great product at a fair price, Recommended.
