FAQ

Prime 9 Box One & Two Installation


Are Box Prime 9 derailleurs compatible with Shimano "direct mount" hangers?

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

Is the Box Two Prime 9 Derailleur compatible with other 9 speed components?

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

Are Box Prime 9 derailleurs compatible with drop bar (road) shifters? 

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.

How should I clean my Box Two Prime 9 derailleur?

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.

How do I make adjustments to the derailleur?
