JACO Superior Products BikePro Bike Tire Pressure Gauge - 160 PSI (Road Bike & BMX Series) | Presta + Schrader Air Chucks

This is a great tire pressure gauge. I've recently purchased an E-Bike. I ride to and from work 5 days a week, and for recreation on the weekends. Improper tire pressure can adversely affect a bike's performance. I check my tire pressure before every ride, so I'm using the gauge almost every day. It's well made, with sturdy, good quality parts. It attaches to the valve stem quickly and securely, and comes off easily, with little or no loss of air. The face is easy to read and as an added feature, glows in the dark when exposed to a light source, such as a flashlight. The reading is locked into place on the gauge until you release it by pressing a button located on the neck. You can also release air from an overinflated tire by pressing the same button. There's a built-in air bleeder valve. It comes with chucks for both Presta and Schrader stems. A rubberized cover surrounds the gauge itself. Mine gets bounced around in the trunk bag on my bike, and I've dropped it a few times with no visible damage or accuracy issues. All in all a great product, for a great price. I would recommend it to any of my friends. By the way, if you have an issue with your purchase or need assistance contact the seller. Their customer service is first rate.

El producto es maravilloso. No le dado las cinco estrellas simple llanamente porque me hubiese gustado que en vez de llegar a 11 bares fuese hasta cinco pero no lo tenían

Out of honesty I have to improve the rating. I have used this for a while now on high pressure bicycle tires, autos and low pressure tubeless mountain bike tires and this works surprisingly well. It’s not high pressure enough for mountain bike shocks. And you have to change the fitting for presto or Schroeder valves. It would be nice if you could keep the fittings and the gauge together on a holder or have a universal fitting to minimize the hassle of swapping fittings. The previous review was probably biased by the gauges I used for comparison assumed were accurate. Previous first impression - This is a quality product. It seems well made and sturdy. I performed an informal comparison of 3 gauges on 8 car tires measuring the pressure before and after adjustment. Of the 3 gauges this one consistently recorded the highest pressure about 0.5 psi above the average (pressure range 28-38 psi). The precision was great and the measurements were reproducible. However, the significant figures over the pressure range of the gauge are variable. The readability of the gauge is 1 psi, but you can tediously extrapolate to 0.5 psi if you concentrate and correct for parallax. So you can see 17+/-1 psi in a mountain bike tire is less accurate than 130+/-1 in a road tire which is why I rate this gauge only 4 stars. Ideally, I would like to have two pressure ranges to choose from.

Having purchased and received this a couple of weeks before even opening the package, it dawned on yours truly it might be a good idea to check it out before its 30 day return window closed; no worries as it turned out. The pressure gauge in addition to arriving in a well packaged shipment turned out to be a genuine pleasure to use which is mainly for its Presta air valve compatibility (for my bicycles' wheels with Presta valves). Also, the Schrader air chuck when used in combo with the air hose that's attached made checking tire pressure on my vehicles easier and far less fussy as compared to all my other pressure gauges. Similar to other air pressure gauges on the market today, it has a very useful pressure release button that at least for me, allows for a more accurate and less rushed reading of the gauge. As far as accuracy's concerned, it's at least as accurate as other gauges I own if not more so. All said along with its rugged looks and seeming robust build quality, it should provide a long useful life, or so I hope.

This is a very well made instrument. I mainly purchased this air gauge for checking the 700×29 air pressure on my Trek road bike. When your dealing with extremly thin tires and psi over one hundred pounds. Overinflating 10 to 20 pounds could cause the tire to explode with tube or the over inflated tube can cause the bead of the tire to seperate. This gauge handles the job just fine. Was hoping the gauge would be smaller so I could take it with me on rides. It easily fits in my large under seat bag but I have seen them half the size. Though there probably not as accurate. Iam one of those that likes to be prepared out there and carry everything but the Kitch.....Also this gauge comes with two different size chucks. One is the standard one we see on practically all pnuematic tires. The other type is mainly for bike tube. Both of these chucks fit firmly on the valve stem. Good product and price
