The Light Weight Champion!

A couple of years ago we decided to make the lightest 10-speed chain in the world. Well, it took us 3 years of developing, testing, re-tooling and re-thinking production methods. We targeted a super light weight chain, but not only for road use, also for all other types of cycling.


This is the reason why it has been tested extensively by many different disciplines, from Road to MTB and Downhill, from X-country to super intensive Marathon tandem use.

We are greatfull to our MTB and Racing test teams and riders who helped us to successfully realise this project. Without their help we we could not have achieved this new level in the Evolution of chain manufacture! We are now able to proudly present our latest creation: X-Super Light.

True racing chain

The X-SL series are the lightest chains in their class, furthermore, because of the weight reduction the chain has many important benefits such as super fast shifting, smoother action and even a significant reduction of "Chain-Suck". This we discovered during our field tests, since the open inner plate construction facilitates the removal of dirt from within the drive train.

The hollow pin is riveted according to our new "LAT STEP" process, sealing the outerplate with an impressive 350 kilo's of pinpower, making it the strongest chain connection in the industry today.

Our test riders loved this chain from the outset. Riding X-SL they discovered the "true racing chain".

Symbolic for Speed

Our double X-bridge® outer plate ensures maximum shifting performance, while our X-SP® treatment in combination with precision tolerances prolongs the chain's life to the maximum.

The X-series are available for 7-, 8-, 9- and 10-speed cassettes, and compatible with all major systems.

Titanium Nitride Coating
Introducing our latest coating technology on X10SL Gold, X9SL Gold, X10 Gold and X9 Gold Titanium Nitride coating in gold colour.

This surface is very hard and super smooth, not only will your chain remain a GOLDEN chain, it is also less susceptible to dirt, easier to clean and therefore retain it's function much longer than regular chains. Don't worry, if you ride an 8-speed drive-train you can also use our X9 Ti-N Gold.

In fact, we are so convinced of the quality of our Ti-N coated chains that we guarantee your satisfaction!

You will find a warranty certificate with every Ti-N coated X10SL, X9SL, X10 or X9 chain.

K710 Kool Chain
   For the "Kool" guys KMC makes this chain with an impressive tensile strength of 1,300 Kg.
   It fits most sprockets/freewheels/cogs and is smooth on the outside so it doesn't get stuck on
   a handrail or coping. It is also available in the K710SL (Super Light) version, which is nearly 20%
   lighter than the K710!

K910 Kool Chain
   The K910 is a bigger version of the K710 Kool chain with a tensile strength of a whopping 1,500 Kg.
   BMX Freestyle has lots of street riders who cannot use a normal chain, simply because the chains are
   not strong enough for their type of riding. KMC makes this Fat Kool Chain for those whose main
   concern is chain strength rather than weight.

Z510HX & Z610HX
   This is a perfect chain for racing and Heavy Duty BMX use, the tensile strength is a good 1,200 Kg. It
   can be used on almost every front sprocket and rear freewheel/Cog. Light but strong, this chain is a
   bestseller in the BMX Freestyle world, but it is also becoming very popular in the mid-high end range
   internal gear hub equipped bikes, because of it's long life and high reliability.

The Special Internal Gear Chain
You may wonder: "What is so special about the chain on my internal gear bike?"

Indeed, most chain manufacturers may agree with you, so they only offer you one model.

Different use, different product

We think differently. A chain for a Rohloff 14-speed internal gear equipped bike has other quality requirements compared with a chain fitted to a children's bike. That is why we have put a lot of effort into the development of non-derailleur chains, which were solely developed for single speed or internal gear bikes. Why? Because people who ride internal geared bikes are all different; some ride once a month, some over 100 kilometres each day. So, different uses require different products.

You do not expect the chain on your expensive bike to be worn down after only 2000 kilometres.

KMC's philosophy also applies here. We want to make products suitable for every kind of cycling requirement; from basic economy to heavy duty long life chains.

Protecting against rust

Our RB (Rust Buster) treatment is a coating of zinc and chrome, protecting your chain against rust, in fact it makes your chain resist rust 500 times longer than a regular chain. Our RB coating meets with the highest international standards on rust resistance.

Furthermore, all models, except the Z51RB, have received a special thermal Long Life treatment to ensure maximum chain life.
So, the next time you forget to dry your chain after the rain: don't worry... KMC RB chains can take it!

Rust. It is the chain's main enemy, it
- reduces chain life; - reduces optimum chain function; - increases the chance of breakage.
