Topeak SmartGauge D2 Digital Tire Pressure Gauge – Presta/Schrader Compatible, 250 Psi/17 Bar, Precision Air Pressure Reader with LCD Display for Bikes, Motorcycles & Sports Equipment

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.

This product is great. It measures the pressure of my tires and shocks with ease and accuracy. It works with both Presta and Schrader valves without changing parts. It has a digital display that shows the pressure in psi, bar, or kg/cm2. It has a rotating head that makes it easy to attach and read. It has an air release button that lets me fine-tune the pressure. The Topeak SmartGauge D2 is a handy tool for any cyclist who cares about their tire and shock pressure. It's small, lightweight, and durable. It runs on a single CR2032 battery that lasts for a long time. It's easy to use and reliable. The only problem is that sometimes I get too obsessed with checking my pressure. It's so satisfying to see the numbers on the screen and hear the beep when it's done. I can't stop myself from using it every time I ride. I even use it when it's not necessary, like when I'm at home or at work. But hey, maybe that's not a bad thing. Maybe I need to be more careful and attentive to my pressure. Maybe I need some fun and excitement in my cycling. Maybe this gauge is the best thing that ever happened to me. If you're looking for a way to improve your performance and comfort on the road or trail, you should definitely try the Topeak SmartGauge D2. It's like having a smart assistant on your bike. Trust me, you won't regret it.

I have been looking a long time for an accurate prseeure gauge for Presta that does not lose air while checking. This is the best I have found so far. It does take a little practice. Once you figure out how to place it and push it on, it works well. I lose exactly one lb of pressure with each check. I don't think you can find a gauge that does better than that. Line it up and push it straight on quickly (but not too much force...just enough). Now for the problem... I was prepared for a problem with the battery after reading other reviews before I bought this. When I opened the package and installed the battery, nothing worked (blank screen). I tried a brand new battery. Still nothing. I was ready to send the unit back! The original battery was fine. I had read a review that had said to remove the inspection sticker that is inside the battery compartment. So, I did and while I was experimenting with the battery again I heard a beep. I noticed that I could move the battery around and hold it in place (without the cover) to get a readout on the screen. So, I cut a small piece of rubber from an old bike tire inner tube and placed it directly on top of the battery (between the battery and the battery cover). I then screwed the battery cover on and everything worked fine. I have not had a quality control issue with Topeak before. Other than this, the unit seems well built and accurate. If it were not for the battery problem, I would have given it five stars. I have a Lezyne alloy drive floor pump with built-in gauge (another excellent product I got through Amazon). The pressure readout is exactly the same on the floor pump and on the Topeak. Since I am pretty sure the pump is excellent quality, this leads me to believe that the Topeak gauge is accurate.

Ottimo prodotto!! Usato sia per mtb. E bici da corsa. La lettura risulta essere precisa e affidabile grazie anche a l’ampio display lcd, Che ne facilità l’utilizzo.

Un ringraziamento ad Amazon, per la sua solita, ed ottima Gestione della spedizione, e comunicazione sul prodotto.

Excellent

微妙な空気圧調整が手軽にできるのはありがたいです。とりわけロードはチューブレス化によって空気圧の要求がシビアになりました。barでもPSIでも測定でき、出発前に調整することで、ロードの乗り心地とパフォーマンスが格段に向上しました。MTBでトレイルを走った経験は少ないのですが、高圧のままトレイルを下ると、バランスが取りづらく転倒しやすくなります。 このエアゲージは操作がシンプルで扱いやすいです。スポーツバイクに乗るなら、絶対持っておくべき機材だと断言できます。

The price is little high

I've tested it with my car digital meter, my floor pump with a gauge and readings are exactly same as this device shows. So accuracy is very on point. I love the fine tunning feature, the size and easy to use. Construction seems to be pretty good quality as well. It is not very small but if I am going for full day and NEED to know my exact pressure it is small enough to pack it in
