Comments about BikeMaster Chain Breaker 420-525:

The use of this product is easy, but my existing chain had no master link and I had to go on line to see that grinding the rivit was necessary. I would like to see some directions just to boost confidence in the user.

BM Chain Breaker

Comments about BikeMaster Chain Breaker 420-525:

I though it would be a tougher tool than it appears to be. Half way thruough the first pin on a 520 chain the collar inside the tool snapped into three pieces. I was still able to get the first link pin out but then I had a heck of a time getting the plunger back in the tool (collar would not budge inside- 3 peices!!). The plunger itself exploded on the second try leaving me no choice but to cut the next link pin out. I've orderd a replacment plunger for the tool and am hoping for better results next time! If it works right it would be a great tool!

Comments about BikeMaster Chain Breaker 420-525:

The first couple of times I used it, the threads were very stiff to turn and overall quality wasn't great, but it still does the job, and it isn't that bad for the price.
