DESCRIPTION
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.
Yes, The Box Four Prime 9 chain has standard external geometry that will work with most existing 8 speed drivetrains.
No, we make a Wide/Narrow Chainring specific for use with Box Four 8 Speed drivetrains.
We suggest removing the chain from the bike and using a soft bristle brush or rag with soapy water or a mild degreaser. We do not recommend pressure washing, strong solvents or de-greasers as they could degrade the surface coating.
