Back in 1974, EK Chains introduced the world's first sealed O-ring chain. Quality is an obsession at EK Chains. In 1997, the company was certified to ISO 9001 quality management standards. This certification recognizes the high standards of the quality assurance system and reinforces EK's guarantee of safety and precision in every product they sell. Research and development at EK Chain has always focused on creating technological breakthroughs and developing original ideas, and a relentless commitment to innovation continues to drive everything they do.
Quadra-X Ring design reduces friction by as much as 40% due to a smaller contact area. The X-ring's 4-point contact patch also offers better sealing than conventional O-rings. Lab tests show the Quadra-X ring chains last 50% longer than a standard O-ring chain.
EK's exclusive CRH pin treatment provides an extremely hard outside coating and softer inside to increase strength and reduce chain wear. The chromium-carbide pin surface coating also offers superior impact and shock absorption while reducing oxidation caused by exposure to nature's elements.
Lightening holes in the side plates reduce the chain's overall weight by 3% without compromising tensile strength. These holes also extend the service life by dissipating heat and helping reduce dirt and mud build-up.
