KMC X10SL Silver

This KMC chain is awesome. I have all Shimano Ultegra components on both my road bikes, but will probably never again go back to the Shimano chains (Ultegra or Dura-Ace). The main reason is not the performance, rather the installation. The installation of this KMC chain was a breeze. I definitley prefer the KMC quick link system over the replacement Pin system Shimano uses. I I have installed several Shimano chains and there just seems to be more room for error becuase the replacement Pin has to be pressed into just the right position or you at risk of the chain breaking apart on a ride. That's what happened to me and caused me to make the switch to KMC. Yes, it was probably my fault when I installed it, but I'm happy I made the switch. The chain, with it's quick link system, was easy to install and feels alot more secure than the shimano chain/Pin did. Performace wise, I would definitely recommend this chain as well. It is compatible with my 10 speed Shimano groupset and performs/Shifts just as well, if not better, than my previous Shimano chains. I have only been a few rides so far, but my drive train feels very smooth.This new chain does come pre coated with a thicker grease/lube like most other new chains out of the package. After doing some research, some people say to clean it all off and apply your own lube, while others say to leave it on for a few rides and clean it off, apply new lube when neccessary. I decided to leave the pre coated grease on and it ran fine and shifted very smooth. After a few rides, I'm just getting to the point where I'll have to clean off the chain and apply my own lube (Tri Flow).Bottomline: Heck of alot easier to install than Shimano chains and performs just as well, if not better.

I have used mainly sram chains (as I have fallen in love with their products) and decided to try KMC after snapping my third sram chain. I am a pretty stout guy and can really put out some torque. I try my best to ride with the best technique but sometimes you just lose focus and forget to shift or whatever. I have ridden this chain through snow, mud, water, and dry dusty conditions. I have around 1000 miles on it. Some reviewers on the different versions of this chain (TNC and DLC) complain about it gunking up, snapping, noisy, and poor shifting. I would call into question their riding technique, the installation process and their service interval. First off that sticky gunk that comes on a new chain IS NOT LUBE. It is a general protectant to keep the chain from rusting or corroding while stored. Get. Mild degreaser and remove every bit of that. Rock n roll has worked best for me and usually only takes about 15 minutes and one soak. Then apply lube that is appropriate for your riding conditions and or area you will be riding.msecondly install the chain properly. I install my own chain on my FS MTB because every time I have had a bike shop do it they tend to add extra links. On some FS BIKES this is appropriate as there is some chain growth through put the cycle but check your bike as everyone is different. Improper installation can cause your chain to slap, snap, shift wrong, and even damage cogs and rings. Lastly, maintenance! Clean, lube, ride, clean, lube, ride! I love Rockne roll blue lube, but your conditions may require a different lube. It cleans and lubes at the same time. I can get 50-60 miles before I even have to think about relubing. Just wipe off the dust after a ride (don't wash if you do you should re lube) and good to go. No noise still shifts like it was new. These are the greatest chains if you do things right! Just remember no one can be perfect 100% of the time and if you get that one defective chain give them another chance. Again these are awesome chains!

I bought a used Colnago with Campagnolo Record groupset last year. After 5000 miles, I was seeing a little stretch in the Connex chain that was on there, so decided to replace it. I looked at a Campy Record chain, but too pricey and requires special tools. The Connex was ok, but it had some noise issues on the 11 tooth cog. I use KMC on all my other bikes, so decided to try the X10SL where the SL means super light. Yes, this chain is lighter than the Record chain. After only one 40 mile ride, I can tell you it shifts well and handles that small cog better than the Connex chain. Only time will tell how long it lasts, but on my other bikes, the X8, X9, X10 chains last about 5,000 miles. Nice chain so far.

I installed this chain about 200 miles ago after putting over 2,000 miles on a SRAM PC-1031 chain. I've also ridden a different bike with a KMC DX10 chain.This chain on paper is a lot different than the others-- hollow pins, chamfered sideplates, and different metallurgy. So it's no surprise the chain is lighter, better and more costly.It's worth every penny. Immediately you will note decreased driveline noise; the 'sewing machine' type of noise is greatly reduced. Shifting also is faster both up and down, and most noticeable on the rear derailleur.

This is a great chain. I installed it on my 105, 10-speed, compact chain-ring equipped road bike.It came well lubricated, so I just put it on and went for a ride. The "magic link" is great - easy to install with just my hands. The finish on the chain is nice (at least right now) - silver and shiny. We'll see how it looks with use.After a quick rear derailleur adjustment, my bike shifts great and runs very quietly.

I have already used on my Trek Superfly and it worked really nice. Is lighter than Shimano's since links are smaller. So far durability does not seam to be an issue. Make sure you clean the oil it covers the chain since is attract a lot of dirt in the trail before you assemble. Once clean re oil with a correct lubricant.
