Commuter Bike Chain Appraisal

KMC S1 Single Speed Bicycle Chain

This is a new-in-box KMC S1 single-speed bicycle chain, manufactured in December 2022 in Taiwan. The item consists of a 112-link steel chain with a silver finish, specifically designed for 1/2 inch x 1/8 inch single-speed drivetrains. It is housed in its original clear polypropylene retail plastic case with full labeling. The packaging includes a 'SnapOn / Z410SO' connector. The labeling provides comprehensive technical specifications, including the KMC American Corporation address in La Verne, California, and the KMC Headquarters address in Tainan City, Taiwan. The chain appears to be in pristine, unused condition, still exhibiting its factory-applied protective lubricant. The construction features standard bushingless design links with rounded plates for smooth sprocket engagement. The retail packaging is intact, featuring a barcode (766759241032), a QR code, and bilingual or international technical details. This model is a staple in the cycling industry known for its durability and compatibility with BMX, beach cruisers, and fixed-gear bicycles. The quality is indicative of modern mass-production standards for high-reliability bicycle components.
