Odd seeing people complaining about how hard it is to break "modern" chains. I've broken a dozen chains ranging from 8-speed to 11 (Shimano, SRAM, and KMC) with my Topeak Hexus X, not a single one was any trouble. Did a couple HG901 Dura-Ace chains recently and a SRAM PC-1130 just last week, every pin came out easily.
