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

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.

Easy to set up and use. I inflated the tyres in seconds, that was well over a week ago and the pressure in the tyres is still very good. This has me confused, because when you read about using Co2 to inflate cycle tyres, it says they deflate overnight, or within a short time. Reading that put me off a bit, so I'm delighted to find that it is not the case. Both tyres are still hard. My only negative is, the small Co2 canister is not big enough to inflate both tyres. You need to use one and a half canister. Finishing on a plus, I'm glad I bought this model with the shut off valve, although more expensive than the other models, it gives you better control over the flow of air going into the tyres. Well worth the extra money. A highly recommended cycling accessory.

Good

Twenty-four hours before I bought this item, I'd received a nearly-identical product from Lezyne: a tiny, immaculate, CO2 bike tyre inflater. Lezyne seemed to get the best reviews, and is a fairly well known marque. I thought I'd chosen the best option available. BUT ... Turned out that the Lezyne inflator has no internal threading, so you can't actually screw it onto a tyre valve, or, more important to me, you can't connect it to a high-pressure air hose or football needle adapter. But you CAN do all of this with the PRO BIKE TOOL device, which is the subject of this review. And it works a treat: an easily rotating "head" lets you screw down onto your valve (or needle or hose or whatever) without having to rotate the entire tool. The lever-style gas tap works perfectly, and although the manufacturers suggest otherwise, you can shut the flow off and keep the rest of the unused CO2 in your canister apparently indefinitely. I was so impressed, I also bought the PRO BIKE TOOL version with a built-in storage canister that can hold a spare CO2 bulb. Gorgeous kit, brilliantly designed and manufactured. Might even try it on my bike next time I need to pump my tyres!

I used this inflator for the first time today and to say I was impressed would be an understatement. The Pro Bike Tool is beautifully made and presented and comes with a comprehensive set of instructions. Upon opening the package the excellent design, manufacture and finish of the product is immediately evident. But how would it work? Attaching the foam collar to a CO2 cartridge and after checking the valve was in the closed position before screwing the cartridge into the tool, the first problem was evident. I was expecting some indication that the cartridge had been pierced, a hiss or tiny leek, nothing. Ensuring the cartridge was indeed fully screwed in, I attached the head to the presta valve on my bike and slowly turned the valve,the tyre started to inflate and the rate of inflation was easily controlled with the valve. There was some icing around the screw on head and ice on the valve but very minimal. The tyre was fully inflated in seconds and I was able to stop and check the tyre pressure through the inflation process. Very, very impressive piece of kit.

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)

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!

Tot nu toe 1x gebruikt, werkt perfect

Completely up to expectation. Found a few days after delivery a cheaper offer!
