Chains

- Heat treated allow steel solid links with solid pins - Compatible with SRAM, Shimano, and Box 11 speed drivetrains - Also compatible with Box`s 7 speed downhill specific drivetrain

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. We engineered the inner link spacing to be a little tighter than other 8-speed chains and is optimized for use with our Box Four Wide/Narrow Chainring.
