Box Two Prime 9 Speed MTB Rear Derailleur

Box Two Prime 9 Speed MTB Rear Derailleur

Classed as Box’s most durable derailleur, this 9 speed rear mech offers super-smooth and consistent operation on your mountain bike. It 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 optimised for 11-50T cassettes and offer durability and performance for the most demanding terrain, just at a lower price.

FAQ

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.
