Sturdy Tool

This chain breaker works great but the handle could be a little bit longer though.. other than the handle being kind of small it works great.

You get what you pay for

I was able to break one chain with this tool. I used it once and it bent the pin on the tool that pushes the pin out of the chain. If you want a chain breaking tool and you don't want to spend a lot, be gentle with this one.

This is a must have tool!

First time using one of these after 25 yrs and man I do not know what I was thinking by using a grinder, punch and hammer to knock the pins out!! This was easy as it gets!

Question: Do you need a vice?
Question asked 2 years 8 months ago
Does this absolutely need a vice to be used or does that just make it easier and it can be simply held in your hand while breaking?

Answer: You don't need a vice the only thing you need is a mean pair of man hands and start torquing on it with a ratchet and it will pop that pin right out

Question asked by JimJones

Question: Will this work as a chain press as well as a chain breaker?
Question asked Over 3 years ago
I'm looking for something I can throw in my backpack along with a few extra links so that way if out in the middle of nowhere and suffer a broken chain I can make a trail side repair instead of having to push my bike back through miles of desert?

Answer: No this would be a breaker only. I would recommend the Motion Pro Chain Breaker/Press/Riveting Tool.
