Strengths: Light.Weaknesses: After only two rides a piece broke of one link . Half of the side plate between the two pins. Just gone.? Had a buddy try and replace the broken link with the spares I had. About an hour ago the chain broke. Lucky I was only about 100 yards away from the parking lot.Bottom Line: Light chains, Not for mountain biking. definitly buy something stronger. XTR , Sram, Ect. I Have already ordered a new Shimano chain.
Favorite Trail: PCMR , Utah.

Strengths: noneWeaknesses: sucksBottom Line: This chain broke on only its third ride -- probably less than 30 miles, all-in. It broke on pretty level terrain without any extreme chain angles.
I've been riding and racing bikes for 30 years, and i've never seen such a pathetic chain. Total crap.
Stay far away from KMC.

Strengths: Cheap, available in colorsWeaknesses: none encounteredBottom Line: Have used for the second have of the season, about 600 miles. Havent had any issues. The powerlink is a little more difficult to remove than SRAM, but not really a big deal. Got for a great price on ebay ($12 w/ shipping). Would not hesitate to use.buy again. Will be replacing with Sram 991 cross step in the spring.

Strengths: Weight, looksWeaknesses: Chain broke on me today, It was really muddy but still. I only weigh 130lbsBottom Line: Worked well for the longest time in normal conditions, but once I took it on a crazy muddy ride it gave out on me. Not sure if I would get this again. Was not fun walking my bike out in the mud.

Strengths: UnknownWeaknesses: Weakness.Bottom Line: I got this bike and chain less than two weeks ago and commuted a few times before finally getting a chance to take it out XC this past weekend. The chain broke yesterday while I was cruising up hill. I was not standing nor cranking hard. I was in the rightmost (big ring) up front and No 4 (counting up from right to left) in back, so I was only a little crossed.
Weight matters but, when it comes to the drive train, strength matters more.

Strengths: Lightweight
Quick Link
Looks goodWeaknesses: Collects mud like no otherBottom Line: It looks the business, shifts great and can go many, many miles...that is, until you reach mud and moisture. Then, it's CHAINSUCK CITY!!
The small holes and link plate cutouts collect and pack mud so bad, every attempted crank rotation will be met with chainstay-shredding, crank-locking chainsuck. If you like steep, granny gear climbing...you'll have to resort to hike-a-bike! My drivetrain is 100% new and this chain simply does not run well in sloppy, mud conditions. I'm a hopeless weight weenie - but I regret saving 55g in this sensitive area.
Verdict? ROAD BIKE ONLY!!!!

Strengths: Good weight to strength ratio, shifting preformance, resistance to stretch.Weaknesses: pricyBottom Line: Have used this chain on my old Epic without problems and now on Stumpjumer. Feels like the last component that's going to fail. Easy maintenance, smoot hrunning, shifting. My last version of the X9SL came in gold which apart from reliability adds to looks.

Strengths: Probably OK if you don't ride hard and/or uphill. Cheap.Weaknesses: Broke twice in a week, used for less than a month.Bottom Line: I don't recommend this chain. It snapped on me twice going up hills. Once I was able to fix it (and the fix only lasted until I made it back to my car, mostly downhill), the other time I ended up walking a few miles. Do yourself a favor and avoid this one.

Strengths: noneWeaknesses: shoddy. wears out very fast and once it wears out it has a tendency to break links.Bottom Line: don't buy this chain if you're looking for something that lasts. I got 2 KMC chains - a 9spd for my mtn bike and an 8 spd for my commuter. Both wore out incredibly fast and furthermore, once the 8spd chain wore out it started to totally break down. chain started skipping, I thought it was my derailleur cable stretching, and then the chain broke, link plate bent... While waiting for a new chain, I replaced the busted link and the next day broke another different link! This is commuting to work - not railing up a mountain.

Strengths: This is the X9 sl silver 9sp. Light weight is the claim to fame and it certainly shifted well.Weaknesses: Weakness. Chain broke under no extraordinary load. Plates were bent and pin pulled out.Bottom Line: I'd say this chain is too light for anything but easy MTBing on a light bike in lightweight terrain. If you ride hard (who doesn't?) you'll break this and smash your knee into the fork. It's rubbish. Nobody from KMC will read this because they couldn't possibly have enough pride in their product to care about its reputation. If you're shopping for a chain, give this one a miss.
Favorite Trail: loco
Duration Product Used: Tested or demo'ed only
Similar Products Used: Various mid range Shimano and Sram, which only ever broke when absolutely shagged.
Bike Setup: Cannondale RZ140 carbon 1 with all the fruit... that's why I was only demo'ing it for a week. Brand new bike with as-new chain.

Strengths: light weightWeaknesses: durabilityBottom Line: seems to be designed for a <160lb rider who does a lot of flat single track, I am not this rider. I will say that I still have not found the ideal chain but I do know that where I like to ride, super light is not advised.

Strengths: light + strong + very intelligent design.
the TiN coating on my SL version seems to help maintain them.
great/reliable concise shifting even under full spazz power.
after paying for the X9 SL chain - i can't help but spend more time looking after my drivetrain (which is a good thing!)
they are as durable, if not more durable than SRAM PG990's.Weaknesses: TiN coating on the rollers appears to wear off in less than 8 miles, works extra great though in those 8 miles.
TiN gold coating is abit blingy/tacky.
chain might be easier to stretch than other lesser brands if you totally mess up your shifting quite often.
the chains open SL design seems to collect more dirt than any other i've used, on occasion.Bottom Line: if you don't mind taking alittle more care of your drivetrain - these chains are the best.
...this review is for the 08 KMC X9 SL chain...
5 flamin' chili's for value - if you can nab it for less than MSRP.
