It’s engineered without O-rings for a slimmer profile and lower drag, while the high-hardness SDH pin surface maintains a tough exterior and a resilient core to resist breakage under impact. The chain includes a connecting (master) link and uses a new anti-kinking design to simplify installation and upkeep.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the SDH pin treatment improve durability?\u003c\/h3\u003e\n\u003cp\u003eSDH (Surface Diffusion Hardening) forms a hard chromium-carbide layer on the pin surface while keeping the interior metal tougher and more ductile.
