Topeak D2 SmartGauge Black/Grey, One Size

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.

As a casual cyclist who enjoys the occasional bike ride around the neighborhood, Topeak D2 has become an essential tool in my biking arsenal. This compact and user-friendly digital tire pressure gauge has proven to be a game-changer for maintaining optimal tire pressure, ensuring a smooth and efficient biking experience. Its intuitive design makes it incredibly easy to use, even for someone like me who isn’t a bike enthusiast.

Its versatility is another standout feature. Not only does it work seamlessly with both Presta and Schrader valves, but its compatibility with a wide range of tire types makes it a reliable choice for various bikes. The large digital display is clear and easy to read, providing accurate pressure readings with just a simple push of a button. The ergonomic shape and durable construction give it a sturdy feel, assuring me of its longevity despite being tossed into my bike bag regularly.

One of the aspects I appreciate most about it is its efficiency in prolonging tire life and enhancing overall riding performance. With precise pressure measurements at my fingertips, I can easily maintain the ideal tire pressure, resulting in a smoother and more enjoyable biking experience. While I may not be a professional cyclist, this gadget has certainly elevated my biking routine, making it a worthy investment for any household with occasional riders like myself.

Good features. Presta or Schrader. Unit swivels for easy reading at different positions. Battery is easy to replace. Reliable brand. Good value. Accuracy matches my SKS guage.

Muy buen artículo, cumple con toda las funciones y adicionalmente es cómoda manipularla por su tamaño. Por ser digital es mucho más preciso, yo utilizo una bomba de pie con manómetro que es de aguja que es bueno pero no tan preciso y a lo último lo checo con este para dejar la llanta de la bicicleta con los PSI exactos que quiero. En mi caso, es importante la precisión porque es una bicicleta de ruta, lo cual la tengo en 95 PSI

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