If you have ever fought with a well seated quick link or clean your chain often, you will appreciate these pliers. I deal with glacial silt that accelerates wear on bike components, so I remove the chain frequently. Nice tool with Park quality.
I've been using quick connect links since they first came out. I clean my chains on a regular basis and these links make the job easier. I've always struggled a bit to get the links off. I tried using my bare hands; works only if the chain is really, really clean. I've tried needle nose pliers; I've had them slip and pinch my hands leaving blood blisters. Then this tool came along. I've only used it once, but it was so easy to use that I have to wonder why I didn't buy it sooner. If you clean your chain often and have a quick connect link, get this tool to make the job easier.
Don't know why I didn't get this tool long ago! It makes it so easy and quick to remove and release quick links! We have S &S coupled single bikes and a coupled tandem for travel and chain removal is a key part of the disassembly and packing process. Every step is time critical when you are traveling and these pliers speed up and simplify the process (and your hands stay clearer too)!
Does it's job just as well as everything else Park Tool makes, it really is quite simple to remove the chain with the quick link setup. Although I'm sure I would be scolded for doing so I also used these to lock the new chain's quick link into place by reversing the process (obviously) - I'm sure this puts strain on the tool that was not intended but it works anyway.
I have removed shimano, kmc, and sram master links easily. I finally broke down and got a pair after getting tired of pulling on strings to release links. These pliers are too big to fit in a flat pack but nice to have at the workstand.
