Box Four 8-Speed Chain

The Box Four chain employs an 8-speed platform in a similar strategy to the Prime 9 but at a great price point. The chain is polished and then chemically treated to achieve corrosion resistance. Box have engineered the inner link spacing to be a little tighter than other 8-speed chains and is optimised for use with Box's Box Four Wide/Narrow Chainring.
