    The Box One cassette brings together all the virtues of the Prime 9 philosophy and distills them into what we feel is our most defining product to date. A unique machined all-steel unibody lattice and alloy support disc have netted us a high-performing, simple, durable and lightweight cassette. We could have exploited a sub 300g weight with an alloy cog but chose to stay true to our value proposition.

    No this will only work with a HG splined Shimano 9-10-11 speed freehub body.

    No, The Box one Prime 9 Cassette is optimized for Box Prime 9 drivetrains and running other component variations can result in poor performance.

    We suggest removing the cassette from the wheel and using a soft bristle brush with soapy water or a mild de-greaser. We do not recommend pressure washing, strong solvents or de-greasers as they could degrade the surface coating.
