Zefal Twin Bicycle Tire Gauge Review

I have an OLD Zefal Presta sensor that still works after 15-20 years! I needed another for a second bike and also liked the flexibility of the Schroeder option. This brand new gauge seems to read about 10psi lower than several other gauges I have. I plan to do a final test with a digital pressure gauge. I'm discussing returning it for another and if it's not better I'll get a refund. 10psi isn't a big deal on a mountain bike, but 10psi on a road bike makes a world of difference, especially when

I had a previous version of this meter (Presta connector only) and was always amazed at the functionality of the meter. The ability to hold a reading after pulling it out of the valve means you don't have to try to take a pressure reading while on the valve. Two valve ports provide flexibility, but the additional Schrader port doesn't work for me, making it slightly larger than the previous Presta-only version I had. Not a big deal, but when you're trying to cram a lot of tools into a small…

I love the design of this gauge. It is ready to use with Presta or Schrader valves without any adjustment. It stores pressure readings so you can focus on making a secure connection to the tire valve without having to read the pressure gauge. It is also very light, light enough to take with you when you travel. Doesn't need a battery. It seems accurate enough for this purpose and I'd rather have this easy-to-read gauge than a more accurate one that I have to read while holding it on the valve…

I blame myself. I read the negative reviews, read the positives, then I went ahead and ordered this tire gauge because it was small, light and cheap enough and I told myself the negative reviews didn't matter. Turns out there were. This is crap and it just doesn't work. Is that a reset button? Yes, it broke almost immediately. Useless as a tire gauge and not even heavy enough to use as a paperweight. I don't write a lot of reviews but I felt like I should use this thing just to discourage other

Small lover can be accurate - 6-8 lbs between it and the factory pump, at 110+ psi so can only be normal air loss - accurate enough for needs; You want to track the exact science of airflow and tunneling of wind particles. In truth, the little boy is reaching for that Presta nipple like he was born for the moment to complete the task at hand. Holds psi readings until you pull the trigger and then are ready to take the other side of the equation; Frankly, if Zephal doesn't know the dimensions of
