WPS’ O-ring and X-ring chains feature quality-engineered technology at economical prices. Each WPS HSO O-ring and HSX X-ring chain is engineered for strength and durability using processes such as shot peening to reduce crack propagation and pre-stretching to reduce elongation. These chains feature higher tensile strength, less friction and longer life. The O-ring chain starts at $55.95, while the X-ring starts at $72.95.
