Box Two Prime 9 9-Speed Chain

The Box Two chain's nickel plating adds both corrosion and wear resistance. All Prime 9 chains have chamfered shifting edges, solid plates and solid pins to safeguard durability. Box's unique inner link spacing is engineered to grab those modern wide/narrow chainrings. Box has chosen to modernise the 9-speed platform due to the chain's spirited reputation.
