KMC X8 8-Speed X-Series High-Performance Bicycle Chain, Nickel Plate/Grey

It was time for a new chain on my road bike and I decided on this KMC X8 and it was a great choice. The chain is very smooth and quiet. Installation is a breeze with the included quick link (and a pair of chain pliers if you have them). The chain ships in a nice plastic container with factory grease for protection from rust. I would recommend cleaning the chain before installing and then lubricating with good chain oil because as the factory grease is good for keeping it protected while in storage, it's not good for your Chainrings. Overall this chain has added more life and response to my bike. Great value for the price for a solid chain upgrade.

Perfect fit and a great upgrade to my electric bike. Easy to install, and the clips locked into place. And to top it off, it looks great and is of higher quality than the factory chain.

Great chain, love the X design, and it Shifts quick and quiet. One note for the seller, the ad says the included quick link is re-usable, but the note that came in the box says NOT re-usable, so which is it?

7-17-24 I recently installed the KMC X8 8-Speed Nickel Plate edition X-Series Bicycle Chain. It didn't solve my shifting issue - but I trust their quality, so it allowed me to eliminate a worn chain as a potential cause of my issue. As I have 5 bicycles, I need to buy a Chain Checker tool soon. ---------------------------------------------------------------------------- 2-21-25 I bought and installed a KMC X8 8-Speed Chain on a 2nd bike. To do that, I first made sure the old one was the right size, by following Park Tool's advice. Putting front and rear derailers in the biggest cogs, and looked at the back to make sure the chain angle wasn't too extreme at the jockey wheels, or too loose and hanging low. I then removed the old chain. - By looking for a removable link - none found, and I've never replaced this one before. So, slowly using a Chain Breaker Tool, (and reversing pin if it got too hard to turn, and straightened the chain), I put the chain in the tool, and removed a pin, to get the chain apart and off. I put on gloves and confirmed the new chain was rated for my bike speed (8X), opened the box, taking it out and laying it down beside the old one, to compare lengths and decide on the right link to cut. I needed a chain a little longer than the original as it wasn't the best length. I cut the new one, and installed it. - I had a wire from a chain breaker, ready to hold the chain ends, while I put the Missing Link in. Then I used chain pliers to fully install the it. That took some time and I had to look at the KMC Installation Instructions to confirm I was trying to squeeze the chain apart to seat the Missing Link. I also looked at the Instructions as I had a question as to how many times a Missing Link can be used. It states a new one should always be used on a new chain. And, that they can be taken apart and assembled together up to 3 times. Once installed, I then shifted through the gears to make sure the derailleurs didn't need adjustment. I kept the old chain (it was still good) and the new links I had removed, in the new chain's box. - It may help me temporarily fix a chain on the side of the road, should it break.

KMC chains are always good quality and almost indestructible if you keep them lubed.

Perfect for my ATB retro mod 1x conversion. KMC makes the best in the game. Don’t cheap out on your chain since it’s so important.

Old chain all stretched, New Chain Good.

Really really REALLY pleased with this chain. I am a casual, but daily rider of older 3 series Treks (with the attendant low-mid level SRAM and Shimano gear sets), and I did not expect a chain to make this much of a difference. I was servicing and adjusting the derailleurs on both bikes and while the shifts were spot on technically, they still felt "crunchy". I did a bit of reading, and that led me to order one of these. OK, chain lives matter. World of difference. Quieter, smoother, more authoritative shifts. Immediately ordered another one for bike #2. Five minute install, quick links, pre-lubricated. So quiet!

La cadena quedó bien. Los cambios van excelente (la cadena vieja ya no hacia bien los cambios). Se siente de buena calidad y súper fácil de instalar con el quick link. Volveré a comprar para mi otra bicicleta.

The perfect replacement chain on my mountain bike. Extremely easy to install by yourself and my ride now feels as new.

Easy to place

First impressions: The chain looks and feels well built. I removed the factory grease, installed it on 1995 Kona Hahanna MTB, put fresh Squirt -dry- oil on it and the chain is performing very well. Very silent ride and very smooth shifting, so far A+. Only used for a week =/- 13kms a day, will update review later for durability.

Well fixed with my 7 speed cycle easy to access! Thank you
