Box Three Prime 9 E-Bike Cassette
No this will only work with a HG splined Shimano 9-10-11 speed freehub body.
No, The Box Three 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 degreaser. We do not recommend pressure washing, strong solvents or de-greasers as they could degrade the surface coating.
