BikeHand Bike Bicycle Professional Chain Rivet Remover Breaker Tool with Spare Replaceable Driving Pin - Compatible with Shimano & Campagnolo - Single to 12 Speed and BMX Half Link

I've never used one of these before and was a bit apprehensive about changing a chain myself. I bought a new Shimano105, 11 speed chain like my old one and a Shimano pliers to remove the quick link on the worn chain. That worked perfectly too, btw. There aren't any written instructions for this breaker so I decided to practice on an extra link, since the chain comes too long. You stick the link on the support part, tighten the back knob against the chain and twist the handle until it pops. Keep going and it pushes the pin completely out. Super simple! Everything lined up perfectly. I had to do it again for length. The grip and handle are comfortable and it feels well made and heavy. Made in Taiwan, too. I don't plan on using it too often so it should last a lifetime. If you're nervous about doing it yourself, don't be. If I did it, it's basically idiot proof. Ha!

Works great. Well made. Heavy duty - in fact I would suggest that this is NOT the chain breaker to take on your ride. This is a leave-it-at-home shop chain tool.Handle is substantial. Easy to use. I successfully (and easily) took apart a SRAM 12 speed mtn bike chain and a KMC 11 speed mtn bike chain. Worked well with both. I suspect it would work just fine with a Shimano chain and (as advertised) Campy.Will be using it on a Shimano chain in a couple of days and I will update this review at that time.

This is a great tool. It is sturdy and easy to use.The screw holds the chain in place and you push the pin out. Perfect

In my opinion, this tool is well made, clever design and much better than the Park tool version!The advantages over the Park tool are an extra pin is included, better handle and it has more features. At the time of this writing, it also costs around half of the Park tool.I just want to add that normally for bike tools, Park tools are excellent and I own several.

Heavy duty, really good quality accurate pin pressNot bad but it's not USA, that's all I'm saying

Very well built. Solid construction. Large handles give good torque making it easy to use.Highly recommended.

Had to shorten a new chain for my bike and this worked perfectly

If you do alot of work on bicycles, you need this tool! Good quality & reasonably priced!

Happy with the quality of the tool. I bought it because I have a 12-speed chain and it was combatable.

Great bit of kit, had a couple of cheaper ones previously that weren't up to the task. 10/10 for this one

Best chain breaker I’ve ever used

fantastic

It’s definitely much better than what I had before. The previous one I had failed to push a 9 speed bike chain pin and broke.This one did it with ease.
