The Box One chain is protected by our dual-coating. We start with Nickel plating which aids in corrosion resistance and then top it off with the “Diamond-Like Carbon” layer. The DLC is as fancy as it sounds; a synthetic diamond nano-coating that turns up the volume on hardness, wear-resistance, and slickness. 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.
