Summary of KMC's chain types

KMC Chain Series

DLC Chain

The DLC series is KMC’s latest and highest-grade chain, and it stands for “Diamond-Like Coating.” This chain features enhanced surface hardness and anti-rust properties. It is a high-end product for bicycles, with a retail price exceeding 10,000 yen.

The DLC chain comes in various colors including black, blue, yellow, and red, allowing for a stylish accent on your bike.

The DLC chain is compatible with 10-speed, 11-speed, and 12-speed drivetrains.

Note: The 12-speed chain is listed as “for SRAM and Campagnolo” on the Japanese website, but the official KMC site mentions “Compatibility: SHIMANO, SRAM, and all other 12-speed drivetrains,” so it should work without issues.

X Chain

The X chain is KMC’s mid-range chain, with the side of the chain shaped like the letter “X,” which enhances shifting performance. Many people associate KMC chains with the X series.

The X chain comes in various color options, including not only the classic silver but also gold and black, allowing for customization of your bike’s color scheme.

The X chain series also has variations:

1. L/EL: Lightweight chain
2. SL: Super lightweight chain
3. EPT: Eco-friendly chain

The X chain is compatible with 6/7/8-speed, 9-speed, 10-speed, 11-speed, and 12-speed drivetrains, so it can be used with almost all modern bikes equipped with gears.

The 12-speed X chain is also compatible with SHIMANO, SRAM, and other 12-speed drivetrains, as mentioned on the official KMC website, so it can be used without any problems.

Normal Chain

The “Normal Chain” is KMC’s entry-level chain, designed for 6/7/8-speed drivetrains. There are no 10-speed, 11-speed, or 12-speed options available in this line.

Although it lacks the specialized features found in DLC and X chains, it can still be used as a standard shifting chain.

KMC Chain Series and Compatible Drivetrains

Let’s take a look at which drivetrains each KMC chain series supports.

The latest DLC chain is compatible only with 10-speed and above, which are higher-end components, but the high-performance and lightweight X chain covers all shifting needs. Therefore, for most users, the X chain would be a good choice.

Since the X chain is lightweight and comes in various grades, for standard use, you can go for the basic model, while if you want lighter weight, you can choose the EL or SL versions.

KMC Chain Series and Color Variations

One of the features of KMC chains is the wide variety of colors available.

The color options differ depending on the series, as shown below.

Even within the same series, the available color options vary depending on the speed.

Nevertheless, unlike other brands, which typically offer only silver chains, the variety of available colors provides ample opportunity for color coordination.
