Strengths: That would be an oxymoron.
Weaknesses: metal integrity, construction, quality control, durability
Bottom Line:
The KMC Z-7E: Worst bicycle chain ever produced.
Inferior metal is bad enough when used in non-critical applications. When cheap metal is used for a component that depends of tensile strength, it's not only frustrating, it can also be dangerous. In the nearly 50 years I have been riding bicycles, I have never encountered a chain break, up until now. Additionally, the bicycle this chain was installed on only had a couple of hundred miles on it, if that. Under no circumstances would I ever puchase another KMC product.

Strengths: nothing I noticed
Weaknesses: skips gears a lot
broke after ~500 miles
Bottom Line:
This review is for the KMC X9.93 XSP
This chain was on the bike when I bought it brand new and after a few months of mainly only trail riding (no serious DH or anything) one of the links snapped and about a month before this it started to skip gears really bad but after inspecting the chain I found no real flaws so I kept going with regular maintenance and everything. Chain was not neglected, it just sucks. Went with a Wippermann ConneX this time so we shall see how this works.

Strengths: Long life, strength
Weaknesses: None that I've found... Well, I finally had to replace it after ~8000 miles of urban riding, yea, it's worn some...LoL
Bottom Line:
This is a review for a KMC XSP-X9 chain. It came on the bike so I don't know the cost of one. I'm gonna guess that it's in the $15 range.
I ride 150-160 miles a week, to/from work and trails on the weekends.
It is toast now and I'm replacing it with another KMC chain. And why not, after 8000 miles it still shifts good, and doesn't jump teeth on the sprockets. More than I can say about the Sram PC-971 which I tried and it jumps on all the rear gears including the ones I never use.
Haven't decided between the KMC X9-73 or the X9-93, both under $35.
I would recommend KMC to anyone looking for a good chain...

Strengths: quiet, shifts quickly, no problems so far
Weaknesses: none
Bottom Line:
This is the best chain I have ever had. Its very quiet and it shifts instantly. I have had no issues with durability, but have only been using it one month.
Weaknesses: I manage to bend them with chain suck (I think that would be true of any chain though....)
Bottom Line:
Could not agree more with the last reviewer re type of chain tested; So X10SL KMC chain, gold links, hollow pins, hollow side plates, and x pattern on side plates.
This chain shifts fast, really fast, smoothes out the drivetrain really well, lasts well in either muddy (tropical) or fine dusty (dry season) conditions. Looks great and does not break. I do bend them though neccesssitating replacement, but that is due to super close tolerance of sram xx and mojo frame, one chainsuck and its stuffed, any chain would suffer this though. So subjectively a great cheap and long lasting product.

Bottom Line:
THE REVIEW IS FOR ::: KMC X9 93::: Chain FIRST I NEED TO SAY Kmc makes different quality chains just like Shimano for example Shimano has low end Hg50 high end Hg93. I will compare with the shimano Hg73 because that is about the same price and that is what I ran b4 this. The kmc chain is much stronger looks better and last longer. This review is just for the x9 93 kmc chain. I am sure if you buy the 6 or 10 dollar chain you wont like it. The low priced chains are for the trekking bikes or city bikes not for the hard xc riders or the race road bikes. If you are going to be pounding on your chain get a good one not a budget one. We all know you get what you pay for. SO PLEASE SPECIFY WHAT NUMBER CHAIN YOU PURCHASED B4 YOU LEAVE A REVIEW!!!!!! IF SOME ONE NEW TO BIKING IS LOOKING FOR A GOOD PRODUCT AND THEY READ ALL OF THESE REVIEWS THEY WILL JUST ASSUME ALL KMC CHAINS ARE CRAP AND THATS NOT TRUE!!! LOOK ITS THE SAME WITH MOTORCYCLE AND ATV CHAINS. So to all tne people thrown off by this reviews check the forums you will find many good riders using kmc and they swear by them
I am using Finish Line ceramic lube. I keep the chain reasonably clean and follow the lube's instructions. The links are perceptibly loose (I can feel the clearance) after about 1000 road miles and, over the total length, the chain is half a link longer than new! I have never replaced a chain with this few miles on it.

Strengths: Many I am sure
Weaknesses: Also many I am sure
Bottom Line:
seeing as how KMC makes 23 different chains, this entire review section seems totally utterly pointless since noone seems to know nor states what model chain they are reviewing, love or hate. I'm no fan of giant Asian industrial monoliths making bike parts, but I'm sure not all their product is crap nor all perfect and exquisite. So if anyone else posts a review here, PLEASE tell us which model chain you are reviewing!!!!!!

Amazing piece of equipment. I had been riding Campy Record on my Colnago. Took it in for tune-up and was told by mechanic to just try KMC chain . . . that I'd like it better than Campy Record.

Strengths: easy to put on
Weaknesses: cheaply made and next to impossible to remove.
Bottom Line:
this review is for the KMC Missing Link. don't use it. period.
if you've got a chain tool on the trail when your chain breaks you'd be better off with some other product. and if you don't, you're not going to be able to get it on your chain anyway. either way, it goes on quickly and easily and NEVER comes off until it breaks while riding and you need it the most. if you put this on your chain, it becomes another link. don't think you're going to use this to easily take your chain on and off.
after trying to remove it unsuccessfully for an hour by compressing the links to either side of it, i tried to break it with my chain tool to get it out, which only bruised and hurt my hands. i ended up having to take out the links to either side of it to get rid of it after i ruined it trying to get it out. what a piece of crap. save yourself time, money, and a lot of frustration.
