X9 9-Speed X-Series Bicycle Chain | Compatible with Shimano, SRAM, Campagnolo and All Major Systems | Nickel Plate

Great chain and fantastic price. For less than half of the price of a 1-1 replacement for the original Shimano on my Trek and with the very positive reviews of this chain I took a shot. I have it installed on my hybrid now and it took less than 15 minutes to remove the original, measure, remove the two links required from this KMC for my fit, put the Missing-Link together, install and test it out. Flawless solution. My original chain was stretched to the limit of tolerances within 700 miles and I hope this one lasts longer. I maintain my bikes and the chain is no exception. Testing this KMC (other than lots of riding) was to test the play any lateral 'looseness' of the chain and to measure the links. Tight feel and perfect measure. No tight links and it was well pre-lubricated as shipped. I did clean and degrease the chain and re-lubricated it with a wet ceramic which I use for my bikes. Now all that is left is a few hundred miles, regular maintenance and stretch testing. I highly recommend the KMC as a solution and will update this review when I have significant miles on it. My riding is training and long touring so the chain condition is very critical for me. I kept the Shimano as a spare after adding a KMC 'Missing-Link' to it for the panniers as my backup spare. Update: After some miles on the chain here is my update. Exactly as expected and smooth. Shifting went great and I needed few adjustments of the derailleurs to get this chain running well on my bike. I did have one oops moment when I first tested it on a ride. I had a constant whiz sound like a maladjusted front derailleur but that was not it. I had missed one slight hard to see guide on the rail derailleur and had the chain over it instead of under it. I had to pull the chain using the included 'missing-link' and it came off with ease. Re-threaded the chain correctly and it is silent as can be. Love this chain.

I've had quite a few of these, which I use on a road bike with rack and fenders for my daily 13-mile commute, which has a couple of medium moderate hills and one short steep one, and during which I sometimes pick up groceries. Which is to say that there is some weight on this bike besides me (165 lbs.). Previously I had 2 SRAM chains that lasted 2000-3000 miles before stretching enough to need replacing; this one lasted a good 4000 miles. Shifting is crisp and excellent, I rarely if ever need to adjust even over 1000s of miles. BTW I live in a dry (Southern California coast) climate and for many years have used ProLink ProGold (https://www.amazon.com/dp/B000VT2HKQ) to lubricate my chains. It is an excellent product that I highly recommend (as does my local bike shop). The KMC master link opens fine with a needle nose pliers (that is without a special pinching tool), but note that if you need to shorten the chain to match your current one, you'll need a rivet tool. And the silver looks nice, if you're into that kind of thing--even if it won't be so flashy after you've lubed it a few times.

This is a great chain that is compatible with 9-speed bikes. Fortunately, I have not needed to replace my bike chain, but this one has a great appearance and looks to be a great fit for my bike.

This chain works great and fit perfectly.

Nice chain, I have them in my mt, bike and commuting bike. I am a heavy rider, 220 lbs. who used to commute on a rail trail most of the way to work (about an hour each way) with trail grit and steep hills so the chain takes a beating. Basically I get 2 years out of these in 4 to 6 hours of commuter riding a week, June to October. After a bit of a break-in the chain shifts smoothly with no skipping. The "quick connect" is just that, quick. I do think I could get it off by hand of need be, unlike another chain I'll review. Old Guy Mt. Bike Rebuild . . . This spring my sig. other got a lightly used $2000 mt. bike from a friend for about $1000 and she took off. We had started mt. biking in the mid-80's and continued into the mid-2000's when family circumstances ate all of our time. So being cheap, I didn't want to fork over $2K for yet another bike (and, I wanted to see how much mt. biking I was actually going to do . . .) so I decided to rebuild the circa 1995 Diamondback that was a trade-in for the one I broke. That faithful two wheeler was fitted with slicks and used for commuting. Here's what I did: New tires - I got three flats the first 4 rides - one three miles out, of course, at the stem where patches don't work . . . So I swapped out my 20 y/o Panaracer Darts (still good !) with some new half-fats, a Trail King Sport Mountain Bike Tire, Wire Bead 26 x 2.2 BW for the rear and a Mountain King Sport MTB Wire Bead Bike Tire - 26 x 2.2 for the front. My old Panaracer's say 2.1 but these two are MUCH fatter, AND the Mountain Kings are NOT 2.2" as the d"escription says, they are 2.0" measured with a caliper at the actual tire. Maybe if you include the knobs it is 2.2 The Trail King IS 2.2 at the tire. That's not a problem, just what i but odd given the manufacturer is the same. The Trail King I put on the back and it just fits at the front of the chain stays on this old school model frame. I hear muted rubbing, not as cool as a playing card in the spokes, but things are quieter these days . . . I put the big tire on the back in that I run 220 (not fat like the tires, not even half-fat . . .) and I wanted more cushion for my hardtail big azzness. Love the tires, tough sidewall, great grip, and you can run various PSI's depending upon the conditions. They look like they will last a long time and at about half the price of many that look the same. Cassette: My 12- 32 was not cutting it on the climbs like it had (20 years ago . . .) so I bought a CYSKY 9 Speed Cassette 9Speed 11-40 Cassette Fit for Mountain Bike, Road Bicycle, MTB, BMX, Sram Sunrace Shimano ultegra xt (Light Weight) for the hub of an 8 speed I had on my light, strong commuting wheels, black, cool looking, but not as strong as I thought on the trails. I broke a spoke first outing and went back to the original, tank rims. Those rims only had a 7 speed hub. Hmmmmm ? . . . What to do ? What to do ? . . . Take the 11 cog off and run it as an 8 speed ! I figured that the cogs would be skinnier on the 9 speed so the 8 speed hub should fit, works fine. However the CYSKY cassette DID NOT come with the lock ring ! (I meant to contact them about that . . . ). I used the one on the old cassette. I had looked at an 8 Speed Cassette 11-40T MTB Cassette 8 Speed Fit for Mountain Bike, Road Bicycle, MTB, BMX, SRAM, Shimano but again, I had expected to use the 8 speed hub AND I think the CYSKY had more gears on the big end which I would be using. When would I be using an 11 or 13 with my small chainring ? I replaced the dérailleur adjustment screw with a long one I bought for about 30 cents at the hardware store, I forget the size. Bring yours in or get a couple different diameters. You will likely find that you will only get a quarter inch or so more adjustment in that the tip of the screw will slip off where it seats. I took the dérailleur off to do this. On the 40 cog the pulley wheel does touch the cog but I don't use that much anyway. If you are going to a 42 cog you will likely have to get a dérailleur extender. CAUTION ! Some extenders only work with certain brands of dérailleurs. Chain: KMC KMC023 X9.93 Bicycle Chain (9-Speed, 1/2 x 11/128-Inch, 116L, Silver/Black) I got this one because the KMC X11.93 , Nickel Plated 116 Link 11 Speed Chain I put on my gal's commuting/gravel bike (she puts in 8 to 10 hours commuting a week !) I had to stand on to get the "quick" connect to snap on. (And I fed it through the chainstay wrong "somehow" (It was late . . . and long past "happy" hour . . . ) so I had to do the whole thing over again. Somehow with some old spokes and some needle nose pliers I got the the "quick" connect apart. The KMC popped in very easily and I even bought the bicycle chain pliers for it but didn't need them. Pulley Wheels: My 20+ year old pulley wheels had been worn down to look like those pointy teeth you see on those benthic dwelling fish with the dangley light on their heads (no flesh shards though . . .). So I got these: Tacx Sealed Bearing Pulleys - Shimano/Campagnolo 11 Teeth. I like the sealed variety due to the gritty, soggy nature of mt. biking. One less tooth than what was on there and they work great. Those aluminum ones look cool but based on reviews I'm not sure if they'd hold up. So this set up worked fine for my mt. biking needs, good for the uphills (I don't remember them being so long !!!) and we have a choice of lift service mountains with downhill courses and it worked fine on those. I don't "fly" much, I like to stay on the ground. (Kudos to those astronauts on two wheels ! More for them.) I have to buy my own equipment and keep getting my health/crash insurance taken away with all the political gaming by those who got theirs . . . And I took off my clip-in pedals that I had been using for 25 years. I found out that the milliseconds of extra time it takes to clip out can do some damage, like 15 stitches in the belly of my left forearm thanks to a fallen over tree whose warn down roots resembled one of Triceratops cousins with all those horns on the crest. I saw things moving in there folks ! It was a puncture/laceration open an inch and a half ! And I was an EMT in the past and attended to all sorts of things. Things in the inside should stay int he inside ! I had to ride out. load my bike and get to the ER. Not fun for a 75 degree summer day. And I hadn't even hit the hard parts yet !!! Also recommended for road and commuter riders are rear view mirrors, The Mountain Mirrycle for mt. bike type handle bars (mounted "down and in" per one clever commenter, (See: First Review)) and for the "10 speed" variety of handle bars (tube pointing back) Hafny Bar End Bike Mirror, Stainless Steel Lens, Safe Rearview Mirror (Black 68 Diameter), mounts in a minute ! Very quickly you get used to a quick glance down to see how close that semi or texting teenager is getting. I may post some pics (of the bike, not my arm) if I can find a 12 y/o to show me how . . . Happy biking !

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!

KMC consistently makes great chains for the price. I've use them on multiple bikes and have never been let down. The master link works awesome and makes installation a breeze. Smoother shifting and a quiet ride with a clean look. I'd never recommend saving $10 and getting an off brand chain. It's not worth it.

This was a good chain for the money.

Keep up the good work

Llego muy rápido y en perfectas condiciones, la cadena llega muy bien engrasada para que su mejor conservación, la cadena que me llegó es la X9 como se aprecia en la imagen que alguien mas compartió, viene con cierre rápido, yo la voy a usar para una transmisión 1x9 y espero me dure mucho tiempo.

Excellent , still on the mtb 5 years on

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.

Exactly what you’d expect from KMC
