Bike Chain and Crank Repair Tool Kit with Bag, Chain Breaker & Link Pliers & Chain Measuring/Checker + Crank Puller, Must-Have for Cyclist for Emergency/Repairs/Removing/Replacing/Maintenance/Gift

several items in kit. Worked perfectly but would suggest a info sheet

I'm going to use these to practice on a junk bike I found, so I don't mess up my own bikes!

Seth from Berm Peak reviewed this item and he had the same experience I did. Search for Ali Express tools and Berm Peak on youtube, he does a way better job of reviewing them than me!Except for extracting ISIS or octalink cranks, this thing does everything it claims to do and very well at that. You can still do it by making some spacers or getting creative though. I was able to extract both a octalink on a specialized with a spacer I made and an ISIS crank with another spacer I already had. The adapter on the tip could use some work. If it had a few sizes and did not fit so loose it would work.The chain breaking tool is awesome. It works and with minimal effort. It also comes with a wire to help you put the chain on. The chain measuring tool works too! I checked two brand new chains and it measures to the tip.Why this pack mounts to a frame is beyond my comprehension though. I just carry a very small light chain breaking tool. If you have to pull a crank on the trail, you have issues that probably cannot be solved out there. I will take this pack and make proper toolkit out of it and leave the tools in my toolbox. Perhaps it is meant to mount to a bike stand?4 stars! -1 star for a lack luster crank extractor.

This is a great little tool kit. The quality seem decent. The chain pliers are the main reason I ordered this and they work great. Everything is stored in one little tool pouch and it's very convenient to carry with you. It's worth the money.

I've only tried the chain tool so far and very pleased to say it worked well for me.

Not sure why but this was heavier than I expected. Maybe because I haven't had a collection of bike tools all wrapped up in a neat little package.I've not had a chance to use any yet, but the look and feel nicely made. I'm still finalizing the installation of a Swytch e-bike conversion kit and may need to pull a crank off for the pedal sensor to better situate it. The chain tool is nice to have too, since the chain was seized up a while back. I freed it up with lubricant and moving the links back and forth but I expect to have to replace the chain before too long.

I am presently surprised with how nice this little set is. The tools are made well, the fit and finish is nice, any the bag is pretty good.You get everything to work on & replace a chain: a chain checker, master link pliers, and a chain breaker. I popped a 12 speed Sram XX1 easily with the breaker.You also get a crank puller, wrench, and 8mm Allen. While my bike doesn’t need this, I can certainly use the 8mm.The bag is pretty nice. I would never use it on bike and honestly, it’s not really the type of tools you’ve need on a ride, but you certainly could if you wanted to.

This is an adequate bike chain repair kit. The chain repair tools included are a chain breaker, master link pliers, wire to hold chain together and a chain checker tool. The master link pliers are good for removing and reassembling the master link on a chain. The chain breaker tool is just okay as there is a bit of a wobble when using it. But was able to remove the pin when shortening a chain. The chain check tool has two increment measurements, which are .75 and 1.0. There is a crank puller tool which was adequate in removing the crank. The crank puller is used in conjunction with the included wrench. Not there is a bit of wobble when using the crank puller. Also included is an 8mm allen wrench, which may be useful to some bikes. Everything in stored in a zippered case which has two velcro straps to secure onto a bike frame.
