Bike Chain Tool - Chain Breaker for 7, 8, 9, 10 Speed Bicycle Chains

My wife and I are retired, and spend 6 months of the year traveling in our small RV. We have a bike rack and take our two 17 year old Schwinn’s along. Biking and kayaking are two of our fave activities! The bikes have received a lot of use, live outdoors, and were starting to look kind of shabby ☹️. So, I decided it was time to show them a little love! Although the chains were cleaned and lubed with Boeshield on a “fairly regular” basis, our time in Florida (particularly camping along the Atlantic and Gulf coastal beaches’ salt air) had taken its’ toll. They were getting pretty rusty, and needed replacement before further damage was done to the gears. So, along with new rim strips/tubes/tires/brake cables/brakes, and cleaning and polishing products, I hit Youtube for guidance and advice. I’d never done any “major bike maintenance ”, and it was fun learning what needed to be done, and how that could be accomplished. That somewhat lengthy preface brings me to chain replacement! I looked at the different offerings for chain breaker tools, and read lots of reviews on Amazon. There’s the “blue bicycle tool company” which is certainly a major player, and very well known. There were several remarkably “cheap” chain breaks at the other end of the “spectrum”, which “by and large” received mediocre to very poor reviews. Then there was ATLIN! The Amazon reviews were consistently praiseworthy, and themes like “high quality”, “great design”, and “easy to use” were expressed over, and over again! In addition, it was priced competitively. I was sold! I purchased the ATLIN chain breaker, and once the new replacement chains arrived set out to upgrading our bikes. In the meantime, I had received an email from ATLIN outlining (in very clear terms) how to use their tool. How thoughtful! The rear wheels were removed from our 21 speed bikes, and I set about breaking the chain. The first break on the old chain went very well, and I felt instantly more confident in my ability to do these maintenance tasks. The second break also went well for sizing the replacement chain. I was concentrating on getting the new chain sized properly (“measure twice/cut once”). Then, a problem occurred. As I was working on the new bike chain, I neglected to extract the last removed pin from the chain breaker tool. It seemed like more effort was required than before, but I just cranked a little harder. Then it dawned on me what had happened! I backed the tool out, and removed the pin in question. Unfortunately, in the process I had bent the tools extraction pin. The “bend” was definitely noticeable when I spun the tool crank. That meant it would be nearly impossible to center the break properly for the next use. I realize ATLIN thoughtfully includes a spare extraction pin along with the tool, and I installed that back-up. The rest of the chain work went fine. My concern was I now didn’t have a back-up extraction pin. I don’t believe I’ll make the same mistake again, but I’d feel better if I could obtain another spare pin. It was my silly mistake that caused this problem, and I was more than happy to pay for a replacement extractor. I try to take care of my tools, but sometimes things happen. This is one of those times. After relaying my predicament to Blake (the owner of ATLIN tools) he graciously offered to send me another backup extractor pin. How wonderful that they were willing to take care of a “user induced” error! What a terrific business model! Thanks to ATLIN for manufacturing a quality tool, and looking after your customers. You owe it to yourself to do business with these folks. They are good people! I wish them continued success.

Guys I finally figured it out. If you ever find yourself in a situation where you got a small cylinder (5.1in length, ~4.5in girth) stuck in a mini M&Ms tube filled with butter and microwaved mashed banana, THIS IS THE TOOL

Great product. Easy to use and the instructions were well detailed. I’m only giving 4 stars because I wish there was a better way to drive the pin out without pushing it all the way through. Even so if there was better way to position a pin to be installed if it does get removed all the way

I came very close to purchasing a premium name chain break tool. However, I read one negative comment on an expensive chain break tool and kept searching until I found this one…yes, it is as sturdy and durable as it looks. I used it to break a KMC hv700 chain on my Fuji Traverse 1.5 24 speed (3 chain ring & 8 speed cassette). This very reasonably priced tool easily punched out the pin on my “narrow” 1/2” x 3/32” chain. I was so happy I went ahead and did a chain replacement on my other bike (I had purchased 2 KMC Z8.1 chains with included MissingLink BR/CL571R, one chain as a spare). This tool paid for itself on the first use! Very happy! (I opted to buy this sturdy looking single tool rather than a cheaper looking “kit” which had extra tools for clicking the MissingLink to lock it, etc….I just put it on and easily click the MissingLing by using the crank and chainring and holding the wheel… no tool needed.) Note: I have no idea about using this tool on “mushroom” type rivets on higher end chains. At first, I had considered buying a higher end chain with “ mushroom” rivets and hardened links. However, I decided that a super hardened chain would likely just wear my cheap Shimano cassettes even faster. So I am very happy to stick with the standard “ narrow” KMC chains and cassettes that I already had.

Thank God I found this tool. I was using a cheap-o thing I got on e-bay, and cranking until my hands seized up. I thought I was just pathetically low on muscle until I tried this one. The difference. The difference. This one takes a reasonable effort, not bad. It works smoothly. It has a nifty opening at the top where you can lift out the chain link with the pin only partially removed without having to wrangle it. The handle is comfortable. It comes with a spare pin which A: I haven't had to use yet, and B: is tucked into the handle so that it doesn't get instantly mislaid. Granted, I was using this to make flippy fidget toys, but I'm pretty sure that anyone using it for actual bike repairs would have the same experience.

Nice finish and feel Looks like a well made tool The first review I read said that the manufacturer used cheap metal and the push pin bent on the first try. Every tool I looked at had some bad reviews, so spending more doesn't necessarily solve the problem. I looked the tool over and read the directions. I didn't see any reason that the tool should fail if used properly. Some observations: Don't use it on rusted chain. If the chain is old and rusty soak it in penetrating oil. If you can't free it up so that it articulates properly, don't waste your time on it. If the tool lines up exactly the push pin shouldn't bend or break. If the push pin is misaligned even slightly, it doesn't take much to ruin the push pin. You shouldn't have to crank down with all your might to operate the tool. Some pins are hammered in and may have a mushroom shape. Take a file and dress the top of the pin to reduce the the rollover. If the tool is really hard to use, something is wrong. My experience so far is limited to removing a chain from a vintage Schwinn single speed bike and reassembling it on a bench for complete cleaning and rust removal. When I tried to reassemble the chain the pin wasn't straight so I put the chain together on its side and tapped the side of a small wrench. That straighted up the connecting pin enough that I could put it in the tool and line every thing up exactly. The tool pushed the lock pin back in place easily. I did have to turn the chain over several times and push with the tool to center the pin in the chain. I have no previous experience with this type of tool. I believe if I break it or ruin it it is probably my fault rather than "cheap" metal.

I bought a different one from another website and the push pin was too large in diameter. So I got this one instead and it's absolutely a solid purchase. It's so easy to cut chains with this tool now. I really appreciate this company etching their logo on the tool because it shows they're proud to put a name on it. Others don't do this. I can see this product lasting a very long time if you decide to put some lubricant to protect the threads(not that they need lube right away). Overall, I'm very satisfied with this product and I highly recommend it because it's such a great value and pays for itself on first use. I've attached a photo of the included instructions for anyone needing to reference it in the future.

I would rate this 5 for all the greatness it is but 1 thing I didnt like and that is its so easy to push the pin or whatever the thing is in between the chain links out completely.On my first try I pushed the pin out all the way.Regyardless I can yet tell this is a very good tool.Its heavy duty,acurate and easyish.I wouldnt recommend to this to new people sorry though it is a 5 star product for non new people.Oh also the handle part isnt too good the part (the screw thing not the pushing thing) is striped.3 stars now.Yet is as low as Il go because it is at least 3 stars Im sure a very great one costs 20 plus dollars.Overall is worth 12 dollars just best if not new at it.
