CO2 Inflator Quick & Easy - Presta & Schrader Valve Compatible - Bicycle Tyre Pump for Road & Mountain Bikes - Insulated Sleeve - No CO2 Cartridges Included

UPDATE (10/05/17)============================= After owning this product just over a month, I have no complaints, only praise. Because of its compact size and ease of use, Pro Bike Tool's CO2 Inflator remains a valued part of my bike maintenance program. STICKING VALVE: In my original post I mentioned difficulty getting the valve to open. That issue has NOT repeated; the valve has worked perfectly every time I use the inflator, which is almost every day. CARTRIDGE LIFE: the other question I had regarding this product was how long a cartridge would last once screwed into the inflator. It does appear to lose CO2 over time, but I would call this loss negligible, losing perhaps 10 PSI over a 7-day period. So it's not a perfect seal, but at just under $1/cartridge, it's manageable and acceptable. REVISED RATING: Product continues to live up to its previous 4.75 star review, and as the sticking valve issue has resolved, I revise my rating to 4.9 STARS. HIGH RECOMMEND. ORIGINAL POST======================== Disclaimer: I've only owned this product for about 2 hours at the time of this writing. Please check back for progressive updates. SIZE/CONVENIENCE: 5 Stars. Excellent Performance I am fanatical about tire pressure, generally, and specifically, for my motorcycle which is my sole transport (Ah, SoCal). So, the first commendation for this product is its size. The whole thing, plus a couple (or 3) extra cartridges fits into a sidepouch of my daypack. Spacewise, VERY economical. Are you a purist bicyclist? The whole setup weighs maybe 7oz (Unit + 1 cartridge) and shares the dimensions of, say, a pack of cigarettes. Please don't smoke. OPERATION: 4 1/2 Stars. Above Acceptable Performance Easy to operate, and to understand how to operate. Device mounts to tire (Schrader valve) as advertised (both Bike and Moto tires). Cartridge mounts to device as advertised. Delivers C02 gas to tire as advertised, with a * (see below). Here are my results: A single 16g cartridge took my mountain bike tire from 17psi to 41.5 psi, AND my motorcycle tire from 30 to 36psi. Total psi output from 1 cartridge: about 30 psi. There have to be lots of environmental factors than can grossly affect that result. For instance, the bike tire was inflated indoors/78F while the moto tire was outdoors/100+F. Would that affect performance? Someone out there must have that answer. * The reason the Operation eval only gets 4.5/5 stars is because the valve got stuck in the off position after I swapped in a new cartridge. So tightly closed I was about to go get a pair of pliers to get it to open when it finally gave in to extreme hand pressure. Yet another environ factor mitigating operation? Who knows, but you might want to check back here for updates to see if it is a persisting problem. ADVICE/TRICK: Make sure the cartridge is screwed in fully. I thought I had done so, but was getting a relative trickle of air coming out the valve. In fact, thought cartridge might be spent. So I gave the cartridge another tightening twist, just in case, and upon re-test the air blasted out as one would expect. Word to the wise, and a suggestion for those interested in tweaking air flow delivery. OVERALL: Highly Recommend with a combined rating of 4.75 stars. Look for an update to this review in about 30 days (including, for instance, how long a partially full cartridge lasts while attached to the device when not in use)

The Company: I spent a good amount of time researching over a dozen of these devices. I've used friend's before, but never purchased one for myself. After a bit of googling, a few videos, and articles, what I found is BIKE PRO TOOL is a young company, comprised of a group of cyclists passionate about the sport, industry, and helpful little tools to make our lives easier. I like that! Anyone who has a passion for their work will always out produce(in quality) someone else who is just in it for the money. Furthermore, I received a followup email from the company as a courtesy to see if I was satisfied with the product and instructions just in case I didn't find them in the box. I decided to respond with comments about my satisfaction on the product and they actually took the time to respond back to me with a personal note. On their website it states that customer satisfaction is a top priority. I believe this to be true. The Product: As for the inflator, I was VERY impressed with the quality of not only the product, but the packaging and direction sheets included. The inflator has a nice weight to it, very solid and constructed of primarily heavy aluminum. The nozzle fits both Presta and Schrader valves and threads on to make a seal. The nozzle spins independently of the body, making connecting easy. Both the spinning action of the nozzle and the movement of the lever have a nice resistance to them and are very smooth. I attribute this to the quality of gaskets and seals inside. Just playing with the lever feels solid and 'expensive'. For the sleeve, its a nice quality foam rubber, better than I expected. Definitely durable and should last many seasons without rotting out. Operation: It's simple in use and design. If you follow the very detailed directions, it works exactly as explained, right down to the small amount of gas escaping when you pierce the canister and prime the head. Most of the operation is common sense, but again, if you have never used one, please read the directions. Of all the CO2 inflators I have used (3 different quality brands) I like this one the best. Mainly because of the lever actuator and quality. It's easy to get a controlled fill. NOTE: A CO2 inflator is not designed to replace a traditional pump. These devices will get you out of a pinch fast, but you MUST refill the tire with conventional air as CO2 dissipates through rubber.

I've purchased two of another brand/model in the past. It worked great when I needed it, it is still a good model. So I offered to order another one when a friend saw mine in use and was amazed at how easy it was to inflate a flat bicycle tire after patching. The one I had purchased at an earlier date went up in price by about $10 and did not include the CO2 cartridge anymore. But this time there were many other models on the market so I had choices. After a lot of comparisons and digging for details (way to much time spent) I settled on the Pro Bike Tool. I am sorry I had to give it up to the friend who asked me to order it. It's very well made/machined, and good looking if that means anything. It has a nice thick pad as well. It also fits both types of valves. I think it has two advantages over the the previous models I bought. It can be screwed onto both style valve stems for a really nice tight seal. It also has the advantage that you can screw it on and off without turing the entire unit, which is impossible with the spokes in the way. The head that goes on the valve turns independently of the rest of the unit. It is also easier to operate one handed. Buy holding the unit in place and slowly turning the lever with your thumb. My other model really needs both hands to operate. And last, the price on this model is about $10 less than the other. A great tool and a nice price. Much easier to stick in a small seat bag than a hand pump and works far better and quicker. You'll probably burn through CO2 cartridges inflating anything you can get your hands on. Next—an air mattress attachment?

Absolute life saver. Works great when your in a pinch, 15 miles from home at 4 am. You either start walking in your cycling shoes, or call the wife and wake her up at 4 am. Neither is a viable option, so your only choice is to get that tire fixed. I ride 20 miles every morning before I get my day started, and I am one of the lucky ones that just do not get flats very often, but on the couple occasions I have gotten a flat. This little inflator made quick work of inflating my tire so I can get home. It doesnt get me the 95 PSI I like to ride with, but it gets enough air in the tire to ride home. I do wish the foam insulator was a little thicker, especially on those cold mornings. Then again its already a tight fit getting all of my emergency supplies in my saddle bag and more insulation around this thing will make fitting everything in the bag even harder. So just wear gloves when you use it. The nozzle is quality made and is still working after multiple uses. Im interested to know what other cyclists carry in their saddle bags. when you write a review let me know what you carry in your emergency kit. Below Ive listed what I carry. Id just like to know what you carry. 2 inner tubes CO2 Inflator with two CO2 cartridges Mini chain breaker chain links A multi tool Patches Drivers License a 20 dollar bill Tire levers 2 Nutragrain Bars - These are for those times when I hit that wall and need a pick me up My house keys New-skin liquid bandage and a couple Band aids - I fell once trying to avoid a car that came around a bend not paying attention. Cut my arm and scraped my legs pretty good. I bled through my White Castelli jersey which to the day I have not been able to get the stain out of and anyone who rides know that Castelli gear is really expensive. So from that day forward I always carry the liquid skin and a couple band aids

For its size, this CO2 inflator is a giant. It is extremely well-made out of aircraft-grade aluminum and should last a lifetime. A lot of people happily ride their bikes and never think about flat tires. It's not IF you get one it's WHEN you get one. And, usually, it's miles from home, raining out, and your fingers are numb from the cold. The only thing you want in such a case is to get back on the road as quickly as possible. This Pro Bike inflator will be more than happy to make sure that happens. In the past, I've always used frame pumps for the inevitable flat tire. While they do a pretty good job, it takes forever to get a road bike tire up to about 100 psi. This, and a 16 oz. CO2 cartridge can do that in about 5 seconds. It can get a mountain bike tire inflated to about 45-50 psi which is more than plenty to get you home. Please don't cheap out and get one of those all-plastic inflators. I used one once and it literally blew up in my hands. While inexpensive, it couldn't take the pressure, I guess. So, I sat there and sat there some more until some bikers came along and asked if I needed help. Although I had a few spare tubes, they're not very useful without air! This tool takes up almost no room in your under the saddlebag or any other place you store things while riding. I always make sure I have at least 4 CO2 carts with when biking. Not just for my use but in case someone else needs a helping hand. Do yourself a favor. Stop reading this and just click on "add to cart" and get one of these. You'll be so happy you did that you'll puncture your own tire just to get a chance to use this!

I purchased this inflator in July and just got my first flat since purchasing it. The inflater worked great - exactly as expected. I love that it is so small and lightweight - very easy to fit into my saddle bag. The Co2 cartridge screwed on easily and I liked how the valve isn't an on/off kind of thing but you can give little bits of air. Like I read in other reviews, make sure to keep and use the red Co2 cartridge cover. It gets extremely cold during the air discharge. Also, the head froze up a little and seemed to stick to the valve - but I just waited a few seconds and it was fine. And you probably know this - it goes for ALL Co2 inflators, but Co2 dissipates through standard tubes much faster than regular air so after you get back from using this, make sure to discharge your tubes, pump with air, and then I do it one more time just to make extra sure that most the Co2 is gone.

The product and the company's customer service are both great. As to the product, I'm not using it for tires, I'm using it with a Growler Saver pressure cap. That item came with a Genuine Innovations Ultraflate, which essentially made it worthless. The Ultraflate let you pressurize the growler one time, then all the CO2 would leak away -- and it seemed to be leaking out of the valve itself, not where the cartridge was seated on the O ring. (Genuine Innovations makes no promises on this score--it likely takes a whole cartridge to fill a bike tire--so this is not their fault, it is the fault of Growler Saver for choosing to package their item with an Ultraflate.) Having to use a new CO2 cartridge every time I wanted a little beer out of the growler = too expensive (after already spending a ridiculous amount on the cap). So then I tried a Planet Bike Airship. Same problem, plus its O ring tore easily, seemed to seat funny or something. This Pro Bike Tool inflator so far has not let any CO2 leak away, so one threaded food-grade cartridge can be used many times. Perfect! It seems to be a combination result from using threaded cartridges only (to which I'm adding a little teflon thread tape) and, more importantly, a high-quality valve mechanism. As to customer service, Mike, the owner of the company, contacted me by email shortly after the inflator arrived to see if I was happy. I told him I was but that mine didn't arrive with a spare O ring like it was supposed to. I told him this is not a big deal -- O rings are cheap -- just tell me what size I needed so I could buy some spares. He insisted that he would mail me some--from the UK--which is excellent customer service. I have nothing but praise for this item and the company. It looks well-made and I assume it is going to last me a long time. If you want a high-quality inflator, I think this is the one to get.

Perfect toll

I haven't used this on a real puncture as of yet but tried it out on a spare presta inner and oh how easy it is. I've tried others in the past but always seemed to be hit or miss. The screw-on fit and lever operation of this inflator ensures no escape of much needed gas. Very pleased with this product and can't recommend it highly enough. A must for your emergency toolkit.

Hands down the best CO2 inflator I’ve used.

Have yet to try it, but the quality seems great! Feels like a quality tool, and I love the sleeve. No frostbite on my fingers!

I bought this with my eyes wide shut,simply thinking that my wrists were painful enough just riding the bike (old injuries), without struggling to use a pump. I didn't know that CO2 permeates through the tube and tyre and that you lose pressure constantly, so didn't realise this is mainly for use when you are out and about and are fixing a puncture/replacing a tube, just to get you home so to speak. However, now I know its intended use I can categorically state that it is superb at its job and can highly recommend it. I've been cycling for decades and have always been prone to punctures, in my bike tyres mainly but elsewhere on occasion I have to admit. There's something very pleasing about being able to inflate your newly mended tube/tyre in 2 or 3 seconds, instead of having to faff about with a silly little pump (I don't care how good you think your mini pump is, it's crap, they all are, I've spent a small fortune on the sh122y little things). This co2 gadgy will ease the process of fixing your tyre fault and getting you home easily. Once you are home I recommend deflating the tyre completely and using a decent pump (12v, available on Amazon) to refill it with air., It will hold pressure as normal then. One last thing I must mention, the first one of these I ordered was a bit stiff to operate, I found it hard to turn the little lever. So, I emailed the seller with a simple enquiry as to whether this was normal, expecting to be told that I should put a spot of oil somewhere or other, (easy tiger). But no, much to my surprise and delight I received a replacement the next day, not just the valve but the entire product. the replacement was much easier for me to operate the little lever, so did the trick, can't ask more that that can I? The first on was just bad luck, one of those things, but the second was everything the reviews I'd read lead me to expect. I recommend this. Bigtime.
