Standard Mount vs. Direct Mount Derailleur Hangers
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?

Can I install this on my bike that uses a b-link for my current derailleur?
A: Yes! All you need to do is remove your old derailleur and the b-link leaving the standard hanger attached to your bike frame. You can now mount your Box Components derailleur directly to the hanger on your frame.
Can I install this on my bike that currently has a direct mount hanger?
A: Possibly, you will need to see if your frame manufacturer or a third party like wheelsMFG offers a standard mount hanger for your frame.
