The Topeak D2 tire air pressure gauge is a small and rugged tire pressure gauge that has been specifically designed for cyclists. While it is perhaps not the lightest gauge around, it does provide a high level of capability. So if you are looking for a pressure gauge for all of your cycling needs, this may be the gauge for you. However check out the pros and cons below before you buy:
- Rated to 250 PSI
- Auto-switch off
- Display in PSI, Bar or kg/cm2
- May take a little practice to consistently obtain good seal
So How Good is The Topeak D2 Tire Air Pressure Gauge?
Accuracy and Pressure Rating
The Topeak D2 tire air pressure gauge is rated up to 250 PSI, which makes it ideal for measuring pressure in most bicycle tires and shocks. There may be some very high pressure shocks that require pressures outside of this range, but they will be rare and so this pressure gauge will be suitable for the vast majority of tasks. The gauge is accurate to ±0.5 PSI, which should be accurate enough for the majority of applications.

The nozzle is a single aperture with selectable settings so that it is compatible with both Presta and Schrader valves. I have used the gauge with both types of valves and have easily achieved accurate pressure readings using both settings. I have also connected to the Schrader valves on my shocks.

The D2 SmartGauge has some useful features included. Firstly, it can display the pressure in a range of units so that you don’t have to worry about converting the pressure on the tire to different units so that you can measure it with your gauge. The gauge will present readings in PSI, Bar or kg/cm2. When you take a reading, the unit will hold the reading after you remove it from the tire to make it easier to look at the pressure. If you are looking at the pressure in place and you wish to adjust it, there is also a useful pressure release button that will allow you to decrease the pressure in the tire in a controlled way. The unit will automatically power off after 30 seconds of inactivity, but you can also use the power button to turn it off as well.

I have used this gauge on a range of items. I use it mostly for my road bike tires as these need the most attention to keep them pumped up to the right pressure, but I have also used the gauge to check my mountain bike tires, the shocks and rear suspension on my mountain bike, and my car tires.

Ease of Use
The D2 SmartGauge is very easy to use, but you might have to play around a little to ensure you get a good seal every time. Initially I found it very difficult to get a seal on my Presta valve, but upon close inspection I noticed that there was a small tear in the seal on the gauge. After sending it back and receiving a new unit I have had no problems forming a decent seal on any valves. Other family members have used this and they have found that it has taken them a little practice to ensure a good seal every time.

I really like this pressure gauge. I have found it to be accurate and allows little to no air to escape when making a measurement. The reading hold is a useful function, as is the pressure release button. The size is small enough to tuck in a saddle bag, so I can take it on rides to check the pressure after flats. All in all, I think this is a great little gauge.
