EK 520MXR/3D 520 transmission chain

Transmission Chain EK 520MXR/3D 520

The EK 520MXR/3D 520 transmission chain is a revolutionary product that combines performance, durability, and innovative design. Thanks to its 3D design and high-quality materials, this chain offers optimal transmission and exceptional resistance, whether on the road or off-road.

• ThreeD®-Dynamic Design 3D
• Chains of the Future

Through a precision forging process, a 3D shape with reduced volume on the outer perimeter is obtained, minimizing stress and allowing for a balance between strength and lightness. In addition, transmission efficiency has been improved through optimal component precision and rigorous assembly.

520MXR

Improved wear resistance thanks to the CHR treatment on the pins. This is a special treatment that prevents the plate from bending due to wear caused by dirt and sand (for example, off-road).

EK's CRH treatment makes the pins extremely hard on the outside and more flexible on the inside, increasing their strength and protecting the chain from wear. It also provides better shock and impact absorption while reducing oxidation caused by natural elements.
