KMC X9-SILVER-116L, Silver, 0.5 inches X 0.39", KMC022

cumplió con mis expectativas, y a un prefio razonable; Es la que viene de fábrica en mi bicicleta hay que recortarla a medida, es normal, solo hay que tener en cuenta eso.

Something interesting that I noticed about the chain I received is that my Park Tool chain checker at 0.00 will not fit between the links, it's close, maybe with some force that I'm unwilling to try, that said, it fits my 9-speed perfectly and I think the initial tightness of the chain is a bonus, it's more time to reach the 0.75% marker. I noticed an immediate improvement on my shifting, perhaps this is from the X design along the sides, regardless, it unquestionably performs better than my original chain.I am no bike mechanic and found removal & replacing the chain easy, you can do this yourself and save some money; this was the first chain that I installed (I used a park tool ct3.2 to break my old chain, recommended and required) I found the master link easy to install once I understood what I was doing (there are old youtube videos that show an old version of the master link that easily clicks in/out, this will not snap in by hand), when the master link is half-way (holding chain, but not clicked in), pedal backwards so the link is now in the top region, center of cassette and chain ring, and give the pedals a forward snap, shocking the link to lock into place, the chain is now fully installed.I don't have a lot of distance on this chain yet, I will report back if there are any issues, I do not expect any issues and recommend this product.

Well made 9 speed chain.Design: The side plates have a diagonal raised area that will ride better along the front derailleur than a flat plate would. The pins have a small divot in the center which is really nice to help center the chain breaker.Construction: This chain appears well made. I did not find any sticky links and everything was well lubed with a storage protectant so that there will be no rust issues before it is installed. Be sure to clean as much of that shipping protectant off the chain, and properly lube it with your favorite lube before you use it initially. The entire chain, with the exception of the pins, is chrome plated, which looks nice and really helps keeping the chain clean. It wipes off easier than a non-plated chain, and the fact that the chrome looks so nice when clean motivates me to keep it clean.Installation: Just like any other chain. One thing you should know is that the pins are fairly tight, and you should have a good chain breaker to make it easier to remove the correct number of links. Break to the correct length, install with the included reusable master link, and lube before first use. Pretty straight forward.Use: It shifts well, runs smooth and quiet, and is easier than most to keep clean. The chrome plating dresses up the bike and looks great when kept clean. The only downside may be htat the tight pins may be hard to break with a trail side repair tool chain breaker.I will likely buy this model chain again when I need another.EDIT (5/21/2018):I am on my third chain of this model. It is now my go-to chain for 9 speed drivetrains. They last a long time when properly lubed, and the chrome plating really does help keep it clean, make it easier to clean, and rust has never been an issue. I will keep buying these as long as I need 9 speed chains!

great on my mountain bike!! Very satisfied !!!

Great to have chains that include the quick link vs some alternatives. Install is like any other quick link chain, with the added bonus of this chain not being directional. Shifting is exceptionally smooth.
