Its Black Tech double-coated alloy steel construction delivers exceptional durability and corrosion resistance, while the included Missing Link enables quick installation. Weighing only 268g with 126 links, it’s engineered for high-performance cycling with compatibility across Campagnolo, Shimano, and SRAM MTB groupsets.

## Description

The Non-Directiol design allows maximum compatibility. The X-Bridge system on the outer plate is configured with precisely articulated angles for quicker and smoother gear shifting, and quieter riding.This chain is compatible with 12x Campagnolo, Shimano and Sram MTB. They are not compatible with Sram road groups, this is due to a difference in pin length. Features: Titanium Nitride (Gold) coated or Nickel Plated (Silver) Includes non-reusable 12x Missing Link Double X Durability Non-directiol Weight: 268g (126 links)

Review: Perfect - It was time to replace my chain and i've used KMC in the past. Time to use one again. Works great. Installed on 2023 Niner Jet 9 RDO with SRAM drivetrain. Cleaned off the factory grease which doesn't work well in dry climates and instead used Dumonde.
Review: Top choice for good 12spd chain - Great alternative to shimano and sram chains and a good price

### ⭐⭐⭐⭐⭐ Perfect
*by J***H on 12 April 2024*

It was time to replace my chain and i've used KMC in the past. Time to use one again. Works great. Installed on 2023 Niner Jet 9 RDO with SRAM drivetrain. Cleaned off the factory grease which doesn't work well in dry climates and instead used Dumonde.

### ⭐⭐⭐⭐⭐ Top choice for good 12spd chain
*by S***E on 21 May 2026*

Great alternative to shimano and sram chains and a good price

### ⭐⭐⭐ Not an original KMC X12
*by H***9 on 5 June 2025*

I strongly suspect that these are Chinese copies, after 300km the chain is already practically at .75% wear
