Pro Bike Tool 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?

This is a great inflator but for two issues for me. These are really just inconveniences, but they cost this tool a star. The first one is having to screw this onto the valve. Not such a big deal until you have to do it three or four times each tire to check tire pressure. My other two inflators just self seal by pressing them onto the stem. The positive thing is that it does not leak any air when tightening down or removing it. But for me, the screwing and unscrewing gets tedious and I have small hands. Might be even more of an issue for man hands. The second thing that is a problem is trying to slide the foam sleeve over the CO2 cartridge. Maybe there's a trick but I cannot get it to slide all the way on. It gets stuck about half way on and no amount of pushing or tugging gets it any further. Maybe it will break in after awhile and loosen up. This was a selling point for me because I have frost bitten my fingers a few times. Over all, this is a well made tool. There is enough weight to the inflator to give the impression of a quality tool but not enough to be concerned about carrying it at all. I love the lever style discharge mechanism. It is very controllable. And it just plain looks good. If not for the necessity to screw this onto the valve, this would be 5 stars for me. All things considered, I still use this one vs my other two that push onto the stem.

I bought this primarily because it was 1) Compact; 2) Had a regulator on the nozzle, which allows you to start/stop the flow of CO2. The first time I used it, it worked like a charm - inflated my flat tire to ~95-100PSI - and still had a bit of CO2 left in the canister. The regulator really helps you control the flow - and possibly have a little extra CO2 left to top it off if you need it later. I'm not sure how long it holds remaining CO2 once opened - my guess is not long - but once opened, the remainder was still in the canister at the end of my ride an hour later. The second time I used it, it appears I may not have sealed the nozzle to the presta valve tightly enough, because when I opened the CO2, the nozzle unseated and all the CO2 was expressed into the air. The rubber gasket that likely seals the valve to presta was stuck on the presta valve and I couldn't get it back into the inflator nozzle. In desperation, I tried to re-inflate again, but without the rubber gasket. Bad idea: it got stuck on the presta valve and ripped the top of it off. Lesson learned: make sure the valve of the inflator is deeply threaded onto the presta valve (which it says to do in the instructions emailed upon purchasing the unit.) I sent an email to Pro Bike Tool asking about the rubber gasket - and within an hour late on a Friday night, I had a response confirming my issue and with no further questions asked, a response that a brand-new unit would be shipped to me immediately. I was really surprised - and impressed with the customer service. Especially since it's highly likely that this was user error on my part. The inflator itself feels really solidly machined - everything is metal. Given my 1st, positive experience using the inflator and the impressive customer service, I'd highly recommend it.

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!

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.

There are many products out there on the market and this is by far the most compact and easy to operate. The only difficult part was deciding if I had a good seal on the valve stem. So I shot a quick burst of air and it went into the tire so I knew we had a good seal. Tool use Anecdote: A buddy was running a low pressure on his front tire because he couldn't get air in from the floor pump due to a blockage (suspected sealant from a tubeless set up clogged the valve core). We went out anyway and 5.5 miles into the ride air burped out of the sidewall of the tire. Luckily I decided to carry all the things I was going to race with the next week so I got comfortable with the weight. I had the pro bike tool and a few CO2 cartridges and put the tool to the test. IT WORKED LIKE A CHARM and the ride was saved! I am a believer of the tool and so were the rest of my crew. They are all getting this tool ASAP for their own personal kits and it's way better than pumping away with a mini hand pump. This tool will get you back on the trail fast.

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.

Not used it at the moment, tucks away in your pocket very easy small enough to go in my tool pack very well made light weight I loved the email I got after purchased from the seller advising on use and life time warranty any issues been asked to contact the seller. I will update when I use the pump. if looking for a co2 pump you will not be disappointed I have now used for the first time on Saturday and it so a lot better than my old one no leaks and the pressure gauge made it so easy to control the pressure and speed of fill. I would advise anyone thinking about purchasing this just do it you will not be disappointed well done pro bike tools

Ottimo gonfiatore di CO2: compatto, pratico e velocissimo da usare. Il rubinetto in metallo è un vero plus perché permette di regolare la pressione della gomma senza sprechi, cosa che altri modelli più economici non fanno. Si monta facilmente sulla valvola, la bomboletta si avvita in un attimo e in pochi secondi la ruota è gonfia. Perfetto da portare sempre in uscita: occupa pochissimo spazio e dà sicurezza in caso di foratura. Un accessorio ben fatto e robusto, che fa esattamente quello che serve a chi va in bici. Consigliatissimo.

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!
