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.
The Box unique inner link spacing is engineered to grab those modern wide/narrow chainrings. Box chose to modernize the 9-speed platform due to the chain's spirited reputation.

They also work well with BMX 3/32" Chainrings and Cogs.
