EK 3D Chain. This chain is tied with the strongest and longest lasting 520 chain out there in terms of strength and longevity. However, it's lighter then nearly every quality 520 chain on the market, yet tied with the EK ZZZ in terms of strength and longevity.
9,400lb tensile strength, yet 2 ounces above the lightest chain we offer. Making this the lightest EK chain we offer, yet the strongest 520 chain we offer.
