KMC DX10 chain - connex-type link??
My road bike has an '05 Ultegra front and rear derailleur and came with a KMC DX-10 chain. I checked the KMC website for any information on maintenance for the chain, but not much luck. There is one link on the DX-10 that looks like it might be some kind of Connex-type tool-free link to remove the chain. The link is a bit larger than the others (to my untrained eyes) and looks to be more irridescent in color than the basic silver/grey of the rest of the chain. Is this a link I can use to remove the chain? If so, what's the best way to remove/re-attach without too much frustration? Tools needed? Etc? Suggestions welcome...
Thought this would be best on the Road Cycling forum, as it pertains to 10 speed chain.

Close examination will reveal the link to be made of two identical halves - each consisting of an outer plate with a pin fixed in one end and an elongated hole in the other. The pin is grooved about 0.5mm from the end, and you will see that the elongated hole is asymetrical. When fitted, each half of the link exactly fits into the other half, with the tension of the chain keeping the two plates located so that the grooves in the pins stay at the small end of the elongated hole. To spring the plates apart, requires the tension to be taken off the link so the pins can now be moved to the large-hole-ends of the elongated plates. Once this is done, the two halves of the link will separate…
Re-fitting the link is much easier, as the tension in the chain is now working to seat the plates correctly in the grooves of the opposing pins…
There, that feels much better…

PS - here's a Useful Tip: (especially when dealing with oily chains) - I always carry a couple of old socks which I put over my hands when I have to deal with chain-work in the field. It saves getting oil/grime ingrained into my hands, and when I remove them by rolling them off so they're inside-out, leaving them inside-out saves getting oil/dirt/grime over everything in the bag.

I have a KMC chain and went to unhook the link but found I could not unlatch it as with a Connex type link. I used a chain break tool to remove the KMC link and replaced it with a Connex connector link. The Connex link was a bit tight. Is anyone else running this setup?
