How do they do it? Every other chain I've used stretches but these don't. This is a replacement for one that had over 5000 miles on it. I bought another one because the first one got a little noisy. That's it. I checked it all the time with my Park chain checker and it wasn't even stretched .75. Shifts great with my SRAM too.
This chain replaced a [$] campy chain. It shifts as well as the Campy unit ever did and I expect it will last about as long. I kept the box so I'll know what to order next time.
I have been using the KMC X10 chain for several years. I ride in the rain during the fall, winter, and spring, so the ability to quickly remove the chain for thorough cleaning is a big plus.
The split link can be a bit tricky to open up so I bought the Park Tool pliers to make the job really easy. I take the chain off, soak it in citrus solvent, clean it with a stiff brush and rag, then lube it with ProGold. Keeping it clean this way seems to extend the life much longer than using the rotating brush and reservoir setup.
The KMC chain lasts longer than the Shimano chain.
I've used SRAM and Shimano chains for my 10-speed setup. They both work well. The KMC I find to be a little quieter and less finicky. It also looks and feels stronger to me, although I have no data to back that up. Making that conclusion based on how flexy the chains feel from side to side. The KMC feels stiffer to me. I've never tried Wippermann Chains but I'd like to. At the price though, the KMC's are my preference for road or MTB use.
I had this chain originally when I bought my new bike. After about 2200 miles I replaced it with Sram PC-1091R (hollow pins). The Sram 1090r is a few grams lighter, shifts smoother and quieter when new but after about 700 miles the chain was stretched like a noodle with moderate climbing. So, I switched back to this KMC, put it through the wringer and been happy with it so far. Just keep clean and lube every 1-2 rides (100 miles) and it runs just fine. So I'll stick with this chain for its durability, the penalty is a few grams heavier.
I tossed this chain onto a sulry cross-check with FSA Pro Road chainrings and a SRAM OG 1050 cassette on the rear. I had problems from the beginning with chainsuck (on a road bike!) if I stood up to sprint while in the small ring. After the chain broke in, the problems went away. Perhaps this wouldn't have been a problem on a stiff race bike, but for this steel beast I'll go back to SRAM or Shimano chains.
I have used KMC exclusively for several years on my Campy equipped bike. These chains shift well and last for thousands of miles if maintained. They are much cheaper than Campy chins and the ability to connect the chain with the provided link. It is much simpler that what the Campy chain requires and you do not need a special chain tool to put on a new chain.
I'm down KMC. The chains are high quality, easy to install with the quick link, and durable. I degrease the chain first using an eco-friendly citrus degreaser. Then after sizing it using the largest cog smallest ring method I install the chain. Next comes a fastidious lubrication using ProGold ProLink which I lightly wipe (mainly to prevent dripping) and let sit for several hours before thoroughly wiping.
KMC chains serve me well in this way and this one is no exception. I put it on my commuter bike and I like the black silver pattern.
Shifts as well as the Campy Chorus 10 speed chain, but doesn't require the special and expensive Campy or Park chain tool to install. Quite, and it shifts well. Durability is questionable through (the earlier version KMC X10 chain had to be replaced after 1500 miles-.551300 miles of wet PNW winter riding).
For years I've used Campy chains on my bikes since they have Record Veloce FSA components . Had good success with them until the last chain that broke twice . Never had one break before . Getting too light ? Now Campy has a new pin system that according to their instructions requires their expense chain tool. So instead of replacing my chain myself I took it to my mechanic to be safe . With this KMC chain I was able to replace it quickly myself and that quick link really makes it a snap . No more pins. The first ride of 73 miles went great with really nice precise shifting and very quiet . I feel I've found a winner.
I've used Shimano and SRAM chains on my wife's bike but intend on switching to KMC . No problems with either brand but I'll give KMC a good test.
Also the KMC side plates look a bit stronger than the Campy chains .
This was the chain that originally came with my bike. Always performed well so when it came time to change I got another one. Have gone through about 5 of them now and have never had issues whether summer or winter, sunshine or snow, so don't see the need to spend extra on a more expensive brand.
I have used the 9 speed version of this chain as well. Both the 9 speed and the current 10 speed versions provided long life and good shifting when routinely cleaned and lubed.
