KMC Chain 8SP X8-Silver/Grey - X8.93

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!

I purchased this to replace a really old and original chain on my Schwinn 24 speed mountain bike. I purchased the KMC X8.99/X8 Bicycle Chain and not only does it look great, it seems to be of better quality than my original. It comes with everything you need, including instructions and a missing link link. Once I had everything measured and popped the pin out, everything from there was pretty straightforward. Got the chain back on, and using the missing link, (which my original did not have) it makes it very easy to connect the chain together, and be on your way. I ended up using a different missing link only because of the color, but the one that comes with with the chain seems of better quality than the one I used. (this is just a recreational bike) The missing link link that comes with it is the same nice silver color as the chain. The chain overall came nicely lubricated, good packaging and fit perfectly after sizing it correctly. My old chain was very old and with this new chain my bike feels different when pedaling. Everything works. Shifting is smooth, no skips or jumps and very quiet. I have already ridden 30 miles on it and am happy I changed it. The chain just overall seems high quality and much nicer than my old chain even when new. Most importantly the compatibility, and fit is perfect on my bicycle. The size and links of the chain match up with my original.

This is a noticeably high performance chain. I'm extremely pleased and I highly recommend it. I have a 2016 Giant Defy road bike. According to their website, the stock chain is a KMC Z7. I found this chain with the same specs, but it has a beveled design to it. Also, it says that this chain is stretch proof, which is the reason why I was replacing the chain. I also replaced my cassette, because after 3000 miles of riding, undoubtedly about a third of that with a stretched chain, the teeth of the cassette were also worn. I went with the same cassette as my stock cassette, the SRAM PG850 8 Speed Cassette, also available here on Amazon for a good price. Shifts with this chain are immediate, precise, and smooth as butter. Up and down the cassette, one or two gears away, the response is immediate and smooth. Shifts with the stock chain was pretty good, but this is a whole new ball game. It's terrific! And it's actually $1 less than the KMC Z7 as of this writing for a better chain! If your specs can use this chain, get it!

Very good chain. But do not buy links that are cheap and will brake jump off sprockets.

The chain itself is excellent. Rides smooth, looks good. Seems durable. That said, the included quick link was defective. The quick links are supposed to snap together hard, with an audible click. The pair included with this chain are loose and sloppy - they just slide right in to their "locked" position with no effort. As a consequence, they slide apart with no effort, and are not secure at all. For anyone with any experience with quick links, this pair acts like a pair that has been reused 100 times. Not a big deal for someone who has spare quick links (I didn't for this size chain), but beware of this potential issue as you may need to return this or buy appropriate quick links separately. Although it is a good idea to keep spares of these anyway.

This is a very nice chain have 1700 miles on it and still have many more to go

Okay, first off I'm not an avid bicyclist. I know very little about bikes, other than what I remember when I was scabbing up my knees as a kid. Recently, a friend gave me a Raleigh 21 speed mountain (I think. It has knobby tires, but no suspension. Low gear, is very, very low) bike. It's old, maybe 20 years or so. It wouldn't shift at all, the derailer's, chain and shifting mechanisms were all gummed up and stuck. Using some solvent and light oil, I got everything moving, and functioning as they should (Thanks Google, lots of good info out there on adjusting 20 year old Shimano derailer's and shifters). After I was done, I went for a test ride. It all worked, just not well. The shifting was super clunky and hesitant, and I was getting what felt like the chain was skipping off the rear cassette (I learned that word on the inter web. Thanks again, Google). I couldn't get in all of the gears, no matter how much adjusting I did. Basically, if I was on the smallest gear on the rear cassette, I the front one wouldn't shift to the far left. If I was on the large gear in back, the front wouldn't go all the way to the right, big, gear on the front. On closer inspection, I found several links of the chain were stuck and not rotating as they should. More solvent and lube. After trying and trying, it became clear that no amount of oil was going to loosen them up. So I came here and found this chain, and threw in the recommended chain tool. 36 hours later, Prime did it's thing, and my new chain and tool arrived. Back to Google to learn how to remove links, and get the chain the right length. The included quick link connector threw me off a bit, as it essentially adds a link back in, after you size the chain. As other reviewers stated, it takes some elbow grease to push the pins out, but nothing too crazy. The tool Amazon recommended worked perfectly. I even used it to push the pin back into the links I removed, and it did the job just fine. Once the chain was on, I took another test ride. All I can say is WOW!!! The old Raleigh feels like a completely different bicycle! Smooth, noise free shifting, and it rides so much smother. There is less effort required to pedal now as well. The gear skipping thing is 100% gone, and I can silently snick into each and every gear, every time I hit the shifter. I was actually a little surprised how big a difference this chain made. It's like a completely different bicycle now. Really, it's that good, and made that big of a difference!!! One side note. I didn't degrease and re-oil the chain as some other reviewers suggested. The oil, lube or whatever it was shipped with seemed about right. It's not super saturated in the stuff, and seems to be a pretty good lube. As the magic link thingy is easy to remove and is reusable, I'll wait until it needs a cleaning, and do it then...

This is a chain for bicycles which have 7- or 8-speed rear cassettes / freewheels. After way too much research and upon the recommendation of two local bike shop mechanics, I decided to try a KMC chain rather than buy yet another expensive OEM Shimano or SRAM chain. This KMC chain turned out to be clearly superior to the OEM chains they replaced, and not just because the old chains were shot (e.g., stretched). - I was a bit skeptical that the X.99 would live up to KMC's claims about its anti-stretch, smoother-shifting, lower noise, etc. technology, but so far I cannot dispute any their claims. Shifting is NOTICEABLY smoother and quieter than before on both bikes on which the X.99 has been installed. The old sprocket hunting on the rear clusters has disappeared, and the shifts from chainring to chainring snap in place immediately rather than take a couple of spins before the chain seats. If I had known that shifting could be so smooth and precise I would have bought new chains long ago. - These chains come with a "Missing Link" link, meaning the chain can be "broken" without having to use a chain breaking tool ... this makes removing the chain from the bike very easy. I can recommend the X.99 chain without hesitation.

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.

Item received as described. Very happy with it. Good quality and looks great. Packaged very securely. Would recommend and buy again.
