Bike Chain Kit, Multi-Function Bike Mechanic Repair Kit, Chain Breaker and Bike Link Plier with Hook, 1/2×3/32 Inch 116 Links with 6 Pairs Bicycle Buckle for 6/7/8 Speed Bicycle, Reusable

This kit gives all the tools needed to replace the chain. There are no instructions, so I would recommend watching a video on Youtube. As others have pointed out, the chain breaker is not the best on the market but it does the job fine. Overall, the entire kit does the job and the chains looks like it's good quality. I would buy this again

Muy buena calidad, desafortunadamente no le.quedo a la medida de mi bicicleta.

I purchased the Single, 6/7/8/etc speed kit in order to replace a chain on an ebike that doesn't have a multi-speed chain but it does have a chain tensioner that's really only there to assist with maintenance on the back wheel. Due to circumstances, it decided it wanted to work as a derailleur instead so it's constantly pushing my chain onto the outer section of the motor hubI really only bought this kit for the chain, the chainbreaker tool, and the master links. I only used those parts of the kit. I did not use the other bits that help spacing the chain or holding it in place while working on it.And those parts of the kit worked like an absolute charm! I was able to quickly (Less than 10 minutes) delink my current chain and pull it off, remove my chain tensioner (using my own hex wrench not part of this kit) put the new chain on, measure it by eye, shorten it a little using the chain breaker so it wouldn't have excessive slack, put the master links in place and finish this project that has been bothering me for months!The tool some people show in pictures and video look different from the one I received as mine is all black and there isn't a slide-over handle but rather it screws into the bottom of the tool. It's much sturdier than I expected given some of the poor reviews. The pin may look misaligned as you crank the handle, this is perfectly normal and it is why you need to make sure you have the chain where it needs to be! Universal rule: Outer section (there are two /_\ on the tool.) is what you want to use for removing links or putting them back together. The inner section that's closest to the handle is what you use for loosening the chain if you accidentally make a link too tight so it no longer swivels freely. Unless you are loosening a chain, DO NOT use the inner section closest to the handle. A neat little function of this tool is the knob on the outside of it. The last tool I used did not have one of these and it made it harder to line up the pin while keeping it stable (turning the crank without that extra piece clamping it could cause the chain to shift in the tool) and that old, unrelated tool ended up ruining my chain by bending the outer sections of the chain inwards, hence my reason for getting a chain with the new tool kit. Once you get the chain where you need it to be, turn that knob and it will clamp the chain in place and it makes things so much easier.I am not 100% bicycle maintenance savvy, but this kit saved me a great deal of hassle and money. If I need to replace a chain in the future, or I just want a backup tool and spare chain, I'd definitely buy this one again!Small edit: The handle on the tool has a little storage space inside it. There was a replacement pin for the tool inside.

The media could not be loaded.  El tiempo de envio fue excelente pero la presentación deja mucho que desear la verdad todo venia suelto dentro de una sola bolsa y en las imágenes del producto se ve que viene cada cosa en su empaque,los eslabones me llegaron incompletos en la descripción dice quwnson 6 pares y solo llegaron 3.en cuanto a la duración y calidad tengo que probarlo

Removing a 20 year old rusted chain. I'm old school and spent a bit of time looking for a master link and one was not found. Luckily the kit includes a chain breaker. I had to tighten the pin in it to get it to work right after a few failed attempts. When loose it wasn't centered on the pin so wasn't able to push it out.Putting the chain back together also straightforward and easy. Look for an assist on youtube if you're not sure.All included at a good price that gets you a new, rust-free chain for more enjoyable bicycle riding.
