The Box Three chain is polished and then chemically treated to achieve corrosion resistance. All Prime 9 chains have chamfered shifting edges, solid plates and solid pins to safeguard durability. Our unique inner link spacing is engineered to grab those modern wide/narrow chainrings. We chose to modernize the 9-speed platform due to the chain's spirited reputation.
