Will break and assemble multi-speed, BMX and 415 chains. Will not break a #41 chain. Some of the newer engine kits are coming with an oversized 415 chain. This will not work on those. If your chain is wider than 0.425 inches (11 mm) it will not work.
Please watch this short video on how to use a chain breaker.

It didn't work so well for me. It ended up falling apart. It wasn't able ot push the pin all the way through wth my 415 chain link.

Compared to other breakers I've owner & used in the past this one is by far the best one! While I have not tried it on 415 chain, the fact it is beefy enough to do that job has meant it did not bend under strain of adjusting my other bike and drive chains! Very easy to use, very RELIABLE.

This breaker allows you to assemble and dissasemble 410 chain. It is a much higher quality breaker than to pos i bought at wally world. That thing worked once and you could only take chain apart.

This is a rather poor-quality chain breaker. It's really convenient when it works, but I have gone through two of these. Each time, I had only used the tool 5-6 times. The problem is that the metal that these are made out of is brittle. Eventually the tool breaks in half after repeated use. This is unfortunate because it is tough to find a quality chain breaker for 415 chain.

The best chain breaker I have ever use. It is very easy to use and for the price it is excellent product!

this is a good product but it did not fit on my 415 chain...i had to cut off the little tabs and file them down then just put it on the back, then it just punched it out and it works...

good product. stayed sharp for first dozen uses. Still works, but takes a little effort to remove chain.
