KMC DLC11 1/2" × 11/128" Chain

Product Overview

The KMC X11 DLC is an 11-speed chain designed for road, mountain, and cyclocross drivetrains. Features Diamond Like Coating (DLC) for reduced wear and hollow pins and plates for weight reduction. Compatible with Shimano, SRAM, and Campagnolo 11-speed derailleur systems and includes a reusable Missing Link connector for tool-free installation.

Key Features

• Diamond Like Coating (DLC) – Ultra-hard carbon coating applied to chain surfaces reduces abrasive wear and friction, extending chain lifespan and improving shifting smoothness

• Hollow pins and plates – Internal material removal in pins, inner plates, and outer plates reduces overall chain weight without compromising tensile strength

• Non-directional design – Chain can be installed in either orientation, simplifying installation and reducing setup errors

• Missing Link connector – Reusable quick-link allows tool-free chain installation and removal for cleaning or replacement

• Mud-shedding design – Optimized plate shaping sheds mud and debris 27% more effectively than previous KMC models, maintaining shifting performance in wet conditions

• Chamfered inner and outer plates – Beveled plate edges improve shift ramps engagement and reduce wear on cassette and chainring teeth

Compatibility and Ideal Use Cases

This chain is designed for 11-speed derailleur drivetrains and is not compatible with BMX single-speed applications. BMX bikes use 1/2" × 1/8" single-speed chains, while this is a 1/2" × 11/128" multi-speed chain with narrower width for derailleur shifting. Best suited for road bikes, gravel bikes, cyclocross, and mountain bikes running 11-speed Shimano, SRAM, or Campagnolo drivetrains. Not compatible with single-speed, fixed-gear, or BMX drivetrains—verify your bike runs an 11-speed derailleur system before ordering.
