Bike Tool with CO2 Inflator - Bike Chain Tool/Torx/Hex/Screwdriver - Bicycle Multitool Kit Compact and Lightweight Repair Tools for Road and Mountain Bikes

Like a lot of bike tools, it has a bunch if very tiny allen wrenches on it that are only useful for tuning, and then the majors which are good for putting on a new accessory, a chain breaker, which I've found useful on more than one occasion. This one happens to have two star sizes, which is nice, but I don't imagine I'll need them. On occasion, I think I've seen a front fork that needs a star wrench for adjustment, but mostly it's been, hex (allen wrench). The CO2 charger is nifty as well, great to have on hand in a pinch, but I still prefer a bike pump with a pressure gauge so I know my psi. What this doesn't have, is a wrap to hold the larger tools in place so they don't flop around while you're turning screws. particularly so with the chain breaker. Tightening the end screws to get a comfortable pressure is something I'd recommend so the tool isn't frustrating when you need it, and it will prevent the other tools not in use from being so floopy, but it won't do anything about the chain breaker swinging around. A hair tie will fix the problem. The high polish chrome is a good idea, as it reduces friction on the tools as you fold them out, the surface won't accumulate dust and grime qute as easy, and makes it virtually rust proof, not that I've ever really had a problem with a half decent tool rusting. I've never seen the Shimano crank face on a tool like this, and I don't imagine that to be an on-the-go repair, that's more of a shop thing. Probably outside of the range of useful tools for these. I do wish it had a 3/8" or 1/4" socket drive on it for taking my wheel off, but that too might be overkill. I've always carried a stubby adjustable wrench in my sack for just that purpose. All in all, the only thing I didn't like about it was the size. It's a little wide to make space for the C02 charger, which to be honest, isn't quite as compact as it could be, they could have made it about a 1/2" narrower. There's also an allen wrench kind of like a nut put onto another allen wrench. I'm sure to lose that eventually. That's just knit picky

These multi-tool kits are useful in a pinch, but don’t expect them to solve all your problems. Like many multi-tool kits, there are some attributes which work and and a bunch that I’m pretty confident no one will every find a practical use for. Then again, depending upon which bike, I have different tool needs, so until I can order a custom kit with only those tools I need I’m relegated to a multi-tool kit just like you.This particular bike tool includes a chain brake tool and a co2 inflator (add your own cartridge) which most simple kits omit. That’s a big plus. The downside - the kit I got was a little too loose for my liking, but nothing a rubber band can’t remediate.Do you need this - yeah, if you ride and wanna have a rudimentary set of mostly practical “in-a-pinch” tools with you then this is a decent kit at a decent price point. It’s small, lightweight, and and worth many times its weight in gold if you actually need it.

The real star of the show here is the CO2 inflator, which I've never encountered on a multitool. Most all other tools are still present, and there's still space to fit the inflator. From the description, the only tool I couldn't find was the valve core tool. It might be there, but I couldn't find it. The only other comment I have is for the CO2 inflator. When I saw the photo I thought the copper colored head was a knob that allows you to regulate the air as you fill your tire. I have one such inflator that has this and I really like it. Unfortunately, this is like most inflators, and air starts flowing as soon as you crack the cartridge. This is just the side of the inflator that attaches to your valve stem, not a knob.

The CO2 attachment says open and close but there is no such action. Once you attached the cartridge, it will finish the cartridge so make sure the tool is full hooked up before you attach the cartridge

Nice very compact bike tool. It will easily fit in your pocket or a small carry pack on your bike. Includes just about anything you could need to make an on the trail repair and so much easier to carry than an assortment of individual tools. I haven’t used the CO2 inflator yet so I can’t comment how that works yet but I did go over my bike with the tool to learn how and where to use each Multi-tool. Very satisfied with this tool.

I'm very impressed with this multitool. Functionally, it's as complete as any I've ever tested.Build quality is excellent.Every single tool in this kit works, and works well.The CO2 inflator is very good, and functions flawlessly.The chain break not only works well for how small it is, it simply works well in general, and that's rare for one this compact.The rest of the individual tools are standard, and dependable.As you can see, this is a compact multitool as well.Really, I can't think of one thing I dislike about this multitool. Some have pointed it out it should have a carrying case, but I disagree; I prefer that it be as compact as possible.Overall:If you want a do-all, compact multitool, this is about as good as it gets.5 stars

This bike multi-tool is the ideal companion for cyclists. This all-in-one solution has 20 functions and includes everything from hex wrenches and screwdrivers to chain tools and CO2 inflators. Because of its small size and lightweight design, it's easy to bring along on every ride, ensuring that you're always prepared for unexpected repairs or adjustments.While the KONG MING CAR bike multi-tool is an excellent addition to any cyclist's equipment, it falls short of perfection due to a lack of instructions and a carrying case. Overall, it's a fantastic product that provides convenience and peace of mind while on the go.
