    FAQ

    Prime 9 Box One & Two Installation

     

    No, Shimano direct mount hangers are proprietary and are not compatible with Box derailleurs.

    No, traditional 9 speed systems use a Cable Pull that is not compatible with Prime 9.

    No, Box Prime 9 derailleurs are not currently compatible with drop bar shifters, but we do offer a clamp for our shifters to mount on some 31.8mm drop handle bars.

    We suggest removing the derailleur from the bike and using a soft bristle brush or rag 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.
