The Box Four Rear Derailleur is the base of Prime 9 Technology that offers an affordable clutch based 1 by 8-speed derailleur that is simple and light; this makes it a perfect candidate for every entry-level bike that traditionally has a 3 by drive-train that is neither durable nor user friendly. 

    FAQ

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

    Standard Mount vs. Direct Mount Derailleur Hangers

    No, traditional 8 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.

    Please see our installation video at https://boxcomponents.com/collections/support

    Q: 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.

    Q: 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.
