🚴 JACO BikePro Tire Pressure Gauge - 160 PSI (Road Bike & BMX Series), Presta & Schrader Air Chucks Review

I have this JACO product and a separate road bike air pump with pressure gauge. I noticed that this JACO product does not show the tire pressure accurately. It turned out that the tire pressure was much lower than it really is, so I got rid of tires with higher pressure than me. I noticed that after inflating the tires, JACO always showed a lower pressure than actual/real in various places. Unfortunately that's not true and I had to leave it unused in the basement. Maybe my product was…

My floor pump is not the best, the cartridge is a bit difficult to connect and disconnect I lose some air when suctioning. I bought this pressure gauge because it's small and easy to check without having to carry around a floor pump. I was hoping it would be easier to detach than my floor pump, with less air loss and meets those needs. It is very easy to turn Presta valves on and off. Minimal air loss. It shows the same pressure as the pressure gauge on my floor pump. So that gives some…

I really like this caliber. It's easy to use and has shown me to be more accurate than the gauge on my tire pump (which was off by about 10psi). It holds every reading until the release button is pressed, making it easy to use in situations where the bike stem is difficult to reach. It's very well built - and that might be its only problem. This tool is probably too bulky to carry in a bike saddlebag - it's much better suited for home use. I haven't used the Schrader adapter that comes with the

What I didn't like about this gauge was the inconsistent air pressure readings. I would inflate my bike tire to 60psi using a JoeBlow Sport pump (it has an air pressure gauge that is part of the pump). I would then immediately compare that inflation to a reading taken with the Topeka air sensor and get a near accurate reading of 59psi. I then deflated a significant amount of air from the same tire and pumped it back up to 60psi using a JoeBlow pump. This was followed by a pressure reading with…

This is a quality product. It appears to be well made and sturdy. I made an informal comparison of 3 pressure gauges on 8 car tires and measured the pressure before and after adjustment. Of the three gauges, this consistently recorded the highest pressure, about 0.5 psi above average (28-38 psi pressure range). The accuracy was high and the measurements reproducible. However, the significant numbers change in the relative pressure range. The gauge is accurate to 1psi, but you can laboriously…

Very well made tool. I basically bought this 700×29 air gauge for my Trek road bike. When you're dealing with extremely skinny tires and over a hundred pounds of pressure. Over-inflating 10-20 pounds can cause the tubed tire to explode, or over-inflated tube can cause the tire bead to detach. This meter does the job well. I was hoping the sensor would be smaller so I could take it with me when I travel. It easily fits in my large underseat bag, but I've only seen half as many of them. Although…

I recently attended a week long bike event where I used several different floor pumps. All pumps indicated that my tires were about ten pounds lighter than my Lezyne floor pump's gauge. The JACO Presta gauge shows a difference of about eight pounds. Since this is close to other pumps, I'm pretty sure my Lezyne pump is off by about 8-10lbs. The Presta JACO brass fitting is very easy to use and does not leak air from my Continental. Presta tubes. The pressure gauge is also very durable and has a…

After buying and receiving this a few weeks before opening the box you realized it might be a good idea to get it before the 30 days were up test are above. the return window is closed; don't worry how it turns out. The pressure gauge, apart from arriving in a well-packaged shipment, has proved to be a real delight, mainly due to its compatibility with the Presta air valve (for the wheels of my bikes with Presta valves). Also, the Schrader air chuck, when used in combination with the attached…

A product that really works! I have used a Shrader chuck for testing car tires and a Presta chuck for road bikes. No tools are required to change cartridges; Simply turn the threaded chuck with your fingers. Both chucks allow you to quickly measure air pressure WITHOUT losing a lot of air when installing or removing the chuck. Without lab quality instruments, I cannot vouch for absolute accuracy. But I did some basic testing. When I inflated my bike tires to 100psi using two different floor…
