The Box Two Prime 9 Rear Derailleur is very similar to the Box One version however, to be more wallet friendly, it offers a non adjustable Tri-Pack™ Clutch, bushing pulleys and some muted finishes. Box Two rear derailleurs are still optimized for 11-50t cassettes and offer durability and performance for the most demanding terrain, just at lower price!

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.

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

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.

Worth the extra money

This is a fantastic derailleur. It is on par if not better then the Shimano XT and SRAM x01. What should make it better is the simplicity of a 9 speed v 12. If you’re looking at Box go with nothing less then this derailleur
