Adding an extra tooth to each of the three highest gears provides increased durability and decreased wear by distributing the load over a larger area! Box Four adapts our Prime 9 philosophy of durability, simplicity, and reliability at a great price point. All sprockets are stamped from steel, given our durable black coating and then the larger sprockets are pinned to each other with spacers for easy installation.

Box Components Two DH 7-Speed Cassette

The Box Two 7-speed Downhill cassette gives you the high range without the weight and bulk of the low. In doing so, we have stacked closely ranged sprockets from 11T to 24T and added a nylon/glass-fibre composite DH block.

Box Components One Prime 9 Chain

The Box One chain is protected by a dual-coating. Starting with a 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. Box has chosen to modernise the 9-speed platform due to the chain's spirited reputation.
