I had this mini Park Tool chain breaker, but it just doesn't have enough leverage for my 11 speed chain. I needed an adjustable wrench on the loop handle to get more leverage. A multi tool version might be even worse.
I was doing a standing start in 42/11 and the (9 speed) chain suffered for it. Rode a few miles, but this one link wouldn't flex completely and the chain would roll off the chain ring. Finally figured it out and attempted to use the Cool Tool chain breaker that works fine on 8 speed chains, but wouldn't break this one. Fortunately, it budged the pin just enough to start flexing and it got me home. My Evo regular, and Serfas mini-tool took the pins out fine. So, yeah, test them to make sure. Once in 11 years but, yeah it happens.
