Bulls-Eye pin: The unique KMC bulls-eye pin riveting provides unsurpassed side plate retention.
X-SP treatment: KMC's extreme stretchproof treatment of pins and plates makes this chain less susceptible to wear caused by sand or other exterior material invading into the chain bearings. Drastically enhancing durability.
High alloy material: Pins and plates, made out of special alloy material, reduces chain stretching and thus prolongs chain life.
X-Bridge: The x-bridge outer plate has been configured with precisely articulated angles for quicker and smoother gear shifting and quieter riding.

I will admit that my last KMC chain wore out fairly quickly but, this one has taken a beating so-far this winter and is showing no signs of wear. Shifts smoothly and runs fairly quietly.

Rated 1 out of 5 by SoreKnee Snapped after 100 miles.
Chain snapped after about 100 miles (side plate had pull off). I was standing up and working the pedals hard, even so I don't think it should have done what it did. This chain had had no bad gear changes as it is on a mountain bike that just been used on the road.

I have try Shimano, Clark and SRAM Chains and although they are really good, KMC plays in another level. I got this chain for my shimano XT 9speed set.
You can notice it when you open the box and grab it with your hands. Perfect built, soft movement, strong, well lubricate, it is just perfection. Easy to mount and unmount, even after hard rides you can un/mount the chain with your nacked hands. This chain is indestructible.
The summary... it is a brilliant chain.

I repaired my friend's road bike using this product as he runs a 9 speed bike and was on a budget. He has since done 2500 miles on it and has no clue what the word maintenance means and its still going strong. Cant argue with those results

Ottima catena, silenziosa, economica, affidabile.
La falsamaglia di cui è dotata è fantastica ma consiglio la pinza per aprirla con facilità.

These chains are easy to take off to clean (no tools required at all) and appear to be indestructible.
I just replaced the chain on my road bike (a KMC X9) with a new one. The chain extension gauge I use showed it slightly under 0.75% extended but if I put some pressure on the pedals it showed slightly over. That was after slightly over 3000 miles of riding. Used these chains on other bikes and never had any trouble with any of them.
A low price for an apparently indestructible product is hard to beat. I'm about to order some more as I just used my last one.

I have been riding a KMC chain for as long as I can remember, and I swear by them. I currently ride with SRAM gears all the way through and the KMC chain performs beautifully. Doesn't stretch much, I done 2000 miles on my bike and changed the chain out of my own free will. Takes about 5 minutes to install, and it sounds gorgeous when you're riding.

I'm a heavy rider (started cycling slightly the wrong side of 20 stone) and was always fearful of the tales I'd heard of chains breaking miles away from anywhere. No need to worry with one of these - my mountain bike came with one fitted as standard and it did me 3000-odd miles before I replaced it. I should have replaced it a little sooner, it was more than 1% extended by then although given along the way I'd effectively figured out how to ride a mountain bike, mashed the gears a few times, and found my tendency to use brute force rather than finesse to get over stuff that seems OK.
I've now got another one on my cross bike and that seems to be holding up pretty well too. My wife's MTB chain (also a KMC X9) has just gone over 0.5% extended so I'm ordering a replacement chain ahead of time.
