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 is a very solid, reliable and easy to use gauge that works well for both higher-pressure road bike tires and lower-pressure mountain bike tires, and for auto tires. It works with both Schrader and Presta valves, with a simple, one-click switch to go between these two standards. I really like the large display, which is much easier to read than the tiny display I had on another, older electronic gauge that eventually failed. I also like the swivel head that makes it easy to see the display from various angles. It's got a rugged feel to it (without being too heavy for bringing along on a MTB ride), and is the proper shape for holding it securely while using. It's a great device ... the best tire-pressure gauge I've ever owned. I only have two nitpicks: One thing that's not obvious is how to use the "bleed" or air release button. If you read the instructions, you'll be fine ... so don't toss them! Another nitpick: With a maximum 250 psi, this gauge can supposedly even handle pressure readings on suspension forks and shocks ... but I wouldn't buy it for that purpose. Since this is a press-on, rather than a threaded chuck, you get too much air loss from a shock to get an accurate reading (I tried.)

A must have item for all cyclists. This is my second purchase of it. I thought I lost mine on a bike trip. I ordered one to replace it cause I find using it essential for proper tire pressure. When I first got one, I had a few issues that I eventually figured out and now I can’t live with out it. I found my original one and now I have two. I am giving the new one to a friend to pass on the stoke.

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.

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.

This is the best gauge I have owned. It works great and is super easy to measure on presta valves.

This gauge is pretty nifty. The swivel head and ability to save the reading keeps you from having to crouch down on the ground. The bleed feature is nice for releasing larger volumes of air, but I mainly perform repeat readings and bleed off 1 psi at a time to fine tune my tire pressure. If I had to pick a negative thing, it would be that if you aren't very careful when placing the gauge on the valve, you get a slight leak in the seal and it can give a false reading. Obviously, the solution is to take your time and pay attention. And really, this is more of a problem with presta valves. Presta seems to be a tough valve to make a good gauge for. Other than that, the gauge seems very well made. The screen is large and easy to read. The audible beeps are loud and easy to recognize. Update: After some regular usage the rubber seal that fits around the valve developed a tear and the gauge was no longer functional. I mailed it off to Topeak with a description of the problem and I had a replacement gauge in a few days. Customer service doesn't get any better than that folks. The new gauge has been perfect, and in fact, the part above where I say you have to be careful seating the valve no longer holds true. I have no problem forming a seal now, which leads me to believe that the other one was torn from the start and I just didn't know it until it became more apparent. At this time I will keep the 5 star rating despite this issue because I feel that a single defective unit is not an adequate representation of a product. Update: It's been almost 2 years and the replacement unit is still going strong. I can see where the rubber seal has taken a beating, but there are no leaks with use. I have no changes to add to my original opinion of the product. Even if the gauge were to fail now, it has been a great value overall. If I could change one thing, I'd prefer common o-ring seals that can be replaced by the customer.

This tire gauge filled right out of the box. No matter what tire I tried to measure the pressure it would only read between four and six psi. I change the battery and got the same results. Using a different tire gauge, I measured tire pressure between 22 and 41 psi on the tires. I tried to measure with this tire gauge. So far I am unable to return this defective product. I feel like I just got ripped off for the $40 that I purchased this car gauge for.

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

Will easily inflate my road bike tyres several times, great product
