Bike Chain Kit, 10 Speed Multi-Function Bike Mechanic Repair Kit, Chain Breaker and Bike Link Plier with Hook and 6 Pairs Bicycle Buckle, Reusable (10 Speed Bike Chain Kit)

The chain thickness measured 6.1-6.3 mm. I think the spec for this 10 speed chain is 6.0 mm. This thickness had no effect on my derailleur to easily shift gears. In fact it only took a few very minor adjustments to smoothly run thru all the gears. The pin removal tool almost maxed out while removing the pins on this new chain. It was way too fragile and it was very apparent to me that this tool was incapable of pin removal on my old chain. In fact it took quite a few good hammer blows using a punch to remove the old pins. Easy to see why folks are destroying the removal tool.

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.

Don't bother with the chain break tool, the chain will break it! First time. Keep a park chain break tool handy

i needed a longer chain to convert my single speed bike over and this one worked really well. it was very easy to use. for anyone considering this just be advised you have to be very precise and sometimes go slow with the chain breaker! if u try and force it to much it will break the breaker its made out of cheap iron and not steel or even alloy but its basicaly a free add on so u get what u pay for its the chain that matters

The media could not be loaded. Sometimes you wonder why there isn’t such a thing as half a star when it comes to reviews. In this case, a simple set of tools to help remove a bike chain, has garnered half a star.I am fixing an old bike and there was a rusted chain on it with no quick link. I’ve never worked on bikes before so when I took the tools out I was a little confused on how they worked. I watched a tutorial and it was simple enough. But what I was watching on the video wasn’t matching what was happening in the field. Off the bat the gripped handle fell off. Not a good start.In order for the tool to work there’s a vice like device that drives a pin out of the bike link. The brackets on the tool that hold the device bent the first time I tried. It was comical how poorly these materials were. I could have managed except for the fact the screw to push the pin out didn’t even line up and wasn’t long enough to even work. Here’s the real kicker though. As I was turning hoping it would somehow in gods name actually work THE HANDLE BROKE OFF. I just laughed.This is seriously a piece of junk. I’d use another word but I don’t think they’d publish this review so use your imagination. Literally junk. I ended up taking a pair of plyers to it and finally snapped the rusty chain off. In order to install a new chain you need those piece of junk tools that are useless right now so I have to take my bike to a store tomorrow.Horrible purchase. Shout out to Amazon for the return and our local Kohls where I can drop it off. Serious yikes here. Don’t order this piece of junk trust me

I was excited to have this whole kit, chain and all the tools needed. unfortunately, the chain breaker doesn't work with the chain supplied - the pin pusher is too wide, and destroys itself and the chain in the process of use. It almost made the whole kit useless - but I didn't want to go through a whole other week of back and forth with return so I decided to see if I could make it work. I did manage to run a dremel over the pin of the chain breaker, narrowing it, then hammered it straight again, making it effectively usable so I could finish the install. Other than the chain breaker tool (which is a critical part of the kit to do the install), the chain, and the magic links and link tool are all fine. If this was advertised as "DIY chain breaker tool and chain" I guess I would be ok with it.

Although there were no instructions, my son figured out exactly what he needed to use out of the kit to repair his bike chain. It also came with a full chain in case he needed to completely replace his. Very pleased with the quality and content of this kit.

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

I would not buy again has halfords are doing a good deal on chains it the moment
