I keep a link in my saddle bag and travel kit for emergency repairs. The links are also helpful if you remove your chain for deep cleaning and lubrication (e.g., wax or wax-based lubes). I have a cheap tool to undo the links, but they snap into place easily if you lock your brakes, apply force to the pedals, and listen for a slight "pop" sound.
It does what its supposed to do. I have ised SRAM chains on my Campy equipped bike for years and their Power Links are easier to use than Shimano, but it is 9-speed vs. 11-speed, so that may account for tools needed on the 11-speed (no tools for SRAM 9-speed). If the Shimano Quick Link isn't installed properly, you'll know it, but still, link took is easier than a chain tool
I installed the Shimano quick link in a new 11 speed Shimano chain. But with the new link installed, it's pivoting properly like a chain link should. So when the chain bends around a sprocket, the quick link is stiff and has a very hard time traveling through the gears. I uninstalled and reinstalled, I lubed it up well, I left it lubed overnight, it just won't pivot as it should. And these things are not cheap! Maybe I have a defective unit but I've rarely run into this sort of problem with Shimano. Of course I think I did something wrong, but it's a pretty simple installation! Chain is facing in the right direction and the quick link is also facing the right direction. I'm stumped. (
Never again is the 1 star rating and indeed, my sentiments. I spent an hour with this link and even tried it off the chain to see if it would couple. A hammer succeeded, but of course, it won't come apart and the pins are likely bent. Thankfully off the chain. I will try the Sram master link next.
Although my first experience with a quick-link connector I was suitably impressed. Using the Park Tool MLP-1.2 Master Link Pliers, installation was easy and has proven reliable,
Got an ultegra chain and one of these little guys to connect it. Very easy process and all is well however the quick link likes to disengage on one of the pulleys creating an annoying clicking sound. Hopefully it goes away after the new cassettes teeth wear down a bit.
Hard to rate this item. It works! It's easy! It's a quick link. Buy a few and carry them with you. When you need them, you'll be glad you have them. If you never need one, that's okay, too. It's light. So...buy it! It works. End of story.
I always used KMC 10 speed chains in the past. I decided to stick with Shimano 11 speed chains with my newer bike. I had a real hard time installing the Quick Link first time around. I always lined up the KMC Missing links and ran in though the big ring and it would snap into place. No such luck with the Shimano Quick Link. I must have tried about a dozen times. It would drop off onto my garage floor. Finally I put it in the small chain ring, small (11 tooth) cog in back and it went into place after I placed pressure on the pedals (I acually rode a few feet) and I heard it click into place. I never had any luck installing a connecting link with tool. Near impossible to get one off without one. Note -these are only good for one application. If you remove your chain, you need to install a new Quick Link (per Shimano). However-no need to remove your chain for cleaning.
I have used SRAM, KMC, and Wippermann Connex connector links in the past with no real installation issues. Nevertheless I recently purchased a Park Tool MLP-1.2 Master Link Pliers which made installation and removal of KMC links an order of magnitude easier. The recent purchase of a Dura-Ace 11-speed chain came with this new Shimano Quick Link instead of the usual pin. I dutifully tried to use the pliers (which work in both directions for installation and removal) to seat the link after partially engaging it. The link would not seat no matter how much pressure I applied to snap it into place. A call to my LBS suggested standing on the pedals and applying pressure. Before trying that, I took needle nose pliers and gently squeezed the outside of the plates to push them inward before trying the MLP-1.2 again. THAT WORKED! The link snapped into place and has worked flawlessly while riding. Ease of removal is TBD.
