Description

The Park Tool INF-2 Shop Inflator is capable of pumping up any bike tire in seconds, offering an appealing alternative to huffing and puffing over a floor pump. Great for bike shops, races, events, and especially useful for seating tubeless tire systems, especially MTB and fat tire setups. Features a durable, dual-sided head that is compatible with Presta and Schrader valves and rotates 360 degrees to access valve stems at any angle. The lightweight body is ergonomically-shaped, with an integrated hook for easy hanging and an easy-to-read built-in pressure gauge (0–160 psi, 0–11 bar) with a protective rubber boot. Built for everyday shop use and 100% rebuildable. The INF-2 must be hooked up to an air compressor with an air hose (not included), and features the commonly-used industrial "M-style" fitting. Since our origins in the back of a bike shop in 1963, it has been Park Tool's sole mission to design and manufacture high-quality tools that empower mechanics and riders of all skill levels to service their bicycles. As with our other 500+ tools, our pedal wrenches are a product of our decades of experience and expertise in the industry, in the shop and on the trail.

    • Pricey, but worth it for an enthusiast
If you’re just looking for an inflator, this is not your tool. This is great for setting up tubeless tires and for fast one handed operation where a floor or hand pump would not suffice. A good tool should pay for itself in how much time it saves, and this will save you time- we are talking 10-20 seconds to fill up a tire, instead of what could be a few minutes, which adds up. Anybody who has set up tubeless tires knows how difficult that can be without the right tools too, and this is the tool you want for that. It’s also easier to attach to the valve than your typical floor pump, so it is less likely to eat your valve cores and gets the air where it needs to go much better than other methods. Of course if you run a fleet of bikes or you’re out there every day, this is going to make more sense than if the dust on your bike isn’t from the trail or road, but for ease of use, speed, relative accuracy (I always check but the gauge is relatively accurate most of the time) and utility, this is a great tool. It’s rugged, mostly metal and I’ve seen these last a long time even in a shop setting if well maintained. ... show more

    • Excellent addition to your home bike shop
The Park Tool Shop Inflator is probably the nicest air tool you'll have in your home bike shop. It is an excellent addition to your tool collection. Like all things Park Tool, the quality is exceptionally high. The tool feels incredibly solid--as you'd expect--and the function is great, as well. You've got a schraeder valve on one side and a presta valve on the other. Important note: the diameter of the presta valve and gasket are adjustable using an allen wrench. It also works well with other types of valves, like thru-valves for using sealant (e.g., Muc-off brand) which are the same diameter as presta. The price is a little high but the value is excellent. Highly recommended. ... show more

    • A Luxury Indugence
This inflator is a complete luxury indulgence for a home shop, but boy-oh-boy, it makes those quirky Presta valves a breeze to fill accurately and quickly. I like the fact that the gauge needle is thin and precise. I compared the reading to my very expensive and accurate drag race tire gauge which came with a calibration certificate, and it is virtually identical. This thing is big and heavy in hand, but seems ergonomically designed, and works on Shrader valves by just rotating the head 180°. So, you can be assured that you are riding with properly inflated tires in just a few squeezes of the handle. If you do happen to go a little over, the release button bleeds a bit of air to zero in on the spec in just a few seconds. This beats any other inflator I have ever tried for bike tires, as it is faster and more accurate. I have a number of Park brand tools, and I have always found them to be of good quality and well designed in almost every case. But what really impresses me is their customer service. They stock repair and replacement parts for almost everything they make. I have a 30 year old bike repair stand, and they had all the rebuild parts for the clamps. I also had a problem with the threaded nut on a crank puller and they sent out a replacement nut right away. They stock all the rubber seals and little parts inside the head of this inflator in case you ever have to rebuild it, but it seems that in my home application that will be a long time from now, if ever. ... show more

    • Like the Snap-On of Bike Tools
I have had so many other inflation tools for my bikes and yes, those all were so much cheaper, but the accuracy, ease of use, and quality of this tool is striking. It does not leak air. I can just leave it attached to the compressor hose and there are no slow leaks from anywhere. This is not the case with other tools I have purchases which leak from all over the place. The gauge is highly accurate and best off all, since there is no dangling head attached to a hose, I don't need a third hand to use this tool. It takes 5-10 seconds to grab this from its hook, attach it either to a shrader or Presta valve, and inflate to an exact PSI. There is no fumbling around and best of all, no pumping. I ride trails almost every day and checking my PSI before every ride is mandatory. Even a few PSI loss can mean the difference between a pinch flat or no flat. This tool saves me maybe just a couple of minutes each day, but add that up over time and I think it is worth every penny. ... show more

    • Extremely good product 👌 excluding on flaw
Comes with pre-taped adapter for attaching to the unit. Simple to use at any angle and still view the gauge. One issue of course is needing to adjust the presta valve head. Pretty simple but you might need to fiddle with it a bit. Uses an 8mm hex key I believe. For the price of this unit it should work properly out of the box! I have a $15 foot pump that has worked fine on Schrader and Presta since I got it. No reason a $140 item should not function equally as well out of box. In the in end I'd probably purchase this again as I'm not aware of anything of the same quality. Other cheaper options don't work very long. ... show more

    • Solid Unit
I purchased this item because I needed a better way to fill bike tires. I have two bikes and needed the presta filler. I was using a schrader tip with an adapter to pump up the tires, but this was a bit of a pain. The dual tip on this inflator makes the adapter unnecessary. One thing I found is that on a presta valve, you need to screw the retaining nut all the way out to fill. I like the gauge feature that makes filling to the correct pressure a breeze. I found that the inflator does not work that well for car/motorcycle tires. Because of its size, it is difficult to get to the nozzles on the valve for the larger tires. I have gone back to my old tip when filling these types of tires. Then I have to check with a separate pressure gauge. Overall, I like the unit and would recommend. ... show more

    • Makes an unpleasant task a joy to do. Treat yourself to the best.
Floor pumps are a pain. The Park tool valve is a pleasure. It’s a task I do several times a week on an expensive bike. Now when I top off the pressure in my tires I feel the way you feel when you use a very good tool. On the basis of another review here I also bought the California Air tools compressor. It’s so quiet! I’ll never put up with the roar of a compressor again. Most of our bike tires have presta valves. The ParkTool valve works great every time. The included directions are misleading. They say: “Press the head FULLY onto the presta valve.” Actually you stand above the tire with the valve stem at the top. Unscrew (open) the valve core. Hold the handle of the INF-2 with one hand and the head in the other and pull the head over just the tip of the valve stem. The rubber seal in the head then rests at the top of the threaded body of the presta valve. It does not go over and onto the main body of the Presta valve the way many floor pumps do. A bit of air is released from the tire as the head seals on the presta valve but who cares because I pull the trigger on the INF-2 and it fills my tire while the watch the easy to read gauge and no air is released when the head is removed. If I were Park Tool I’d rewrite those instructions and illustrate the proper positioning. One reviewer suggests using a drill to enlarge the opening of the rubber gasket. It apparently worked for him but it’s totally unnecessary. I’ve used this on several different tires on our bikes and even the schrader valves on our Townie bikes and all work perfectly. Do your self a favor. Buy one! ... show more
