JACO BikePro Bike Tire Pressure Gauge - 60 PSI (MTB 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.

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.

The gauge is built like things used to be. Solid brass nozzles and fittings, real rubber hose, beautiful dial. I love the bleed-off feature to dial in the pressure. I like that it retains the reading until you choose to clear it.A couple of issues:- The presta nozzle did not have the silicone liner installed. The liner was loose in the schrader attachment tube??? Without a diagram or instructions, it made no sense what it was or what to do with it.- No instructions or assembly diagram. Again, what should I do with this silicone tube? By dumb luck and trial-and-error, I finally figured out it was the presta stem sealNice to haves:- a carrying case would be ideal. This thing is bulky and heavy.- a place to store the spare nozzle. I am sure to lose whichever one I'm not using. If I store it somewhere safe, I'll never have it with me. It would be nice to be able to at least clip it to the hose, or better yet, provide a carrying case with a spot for the unused nozzle- a spare silicone tube would be nice, now that I know it's a seal that rubs on the presta threads and may eventually wear.Once I figured out where to put the silicone tube, things worked great. I haven't checked accuracy with multiple other gauges, but I am prone to assume this is the most accurate.In all, a great gauge, but a carrying case would make it near perfect.

Heavy and well built the way tools were built all the time years ago. Gauge has a thick rubber coating for protection with a bleeder valve and glows in the dark should the need arise. 12 in. hose with brass fittings. Connects well with little loss of air when removed. A great addition to the toolbox

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.
