Topeak Smart D2 Digital Gauge - Black

Q: Will this work on Presta and Shrader valves?

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.

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

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?

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.

A good tool to measure the tire pressure on the go

The pressure readout is fairly accurate and the gauge helps in adjusting the pressure too.

Suitable only for bicycles 🚴

Described to be suitable for cars and SUV’s but after testing the reading is fine but the deflation button is way slow.. will take all day to deflate with this gauge… i would only recommend this gauge for bicycles..
