This Premium lightweight PYC bike chain is a chain for 12-speed bikes. The chain has a wear-resistant surface treatment as standard. But this Premium version has had an additional treatment called Chrome Harden Tech. This treatment increases the hardness of the chain components, which greatly improves the durability and longevity of the chain. The pins in the chain are hollow, in order to make the chain slightly lighter that way. The size of the bike chain is 1/2 x 11/128 inch and has 126 links. Suitable for Shimano, Campagnolo and SRAM derailleur systems, including connector link.
