If you’ve ever needed to get an endless drive chain apart, you know it’s a good thing to have a specialized tool to drive the sometimes quite stubborn pin out after you’ve ground the top off. Featuring a chrome-moly body and a folding handle for easy storage, the Mini Chain Breaker belongs in any home-mechanics toolbox. Handles 420, 428, 520, 530, and some 630 chains, which pretty much covers whatever you may run into. Capable of pushing a link pin completely through the connecting link, the replaceable drive pin is heat-treated and very tough. Add the Mini Chain Press (sold separately) for pressing on pressfit side plates. These tools are small and light enough to carry on trips yet tough enough to do the job and get you rolling again if you must do an emergency chain-ectomy somewhere that’s nasty. Press includes hex wrench, and fits all 520-530 size chains. Breaker is 4.5"×1.5"×1", 11.2 oz. Press is 2.25"×1.5"×1", 7.3 oz.
