Wippermann ConneX Links - 10 Speed

I recommend this product

Have used these quick links (and others, but don't compare) for over 5 years now on x4 different bikes with Shimano groupsets. Apart from one wearing and binding up (once), I've not had one fail and hope that never happens. They wear extremely well, but still tend to change them regardless every other new chain so approx every 3-4000Km. These should be used with 10 speed chains, however, I have used them extensively with Shimano Ultegra 11-speed chains, mostly for racing. Pretty certain they shouldn't work, however, have been using them for the last 3-4 years no problem whatsoever. Only thing would say, on the 11t (rear cassette), the link does appear to trip slightly every revolution, but how much do we all use the 11?! Using them with 11 speed is such a hack compared to how much the 11 speed version link is!

I got these to replace KMC Missing Links. I swap between two chains on a regular basis and these connectors are so much easier to insert & remove - no tools needed - and because of the design the links can be undone multiple times without damage or wear. Recommended!
