Our Box Four tier is for those people who just want less fuss! You're fond of Prime 9, but know 8 is enough, and surely 11-42T is plenty of range for an 8-speed cassette. Our derailleur still has the Limited Slip clutch but now arrives with a more compact cage. The custom 8-speed chain is built for abuse, although it's sophisticated enough to have its own Wide/narrow chainring. Push through fewer gears with a no-nonsense shifter. This combo will transport you to 1 by territory for less than $200.

No, Shimano direct mount hangers are proprietary and are not compatible with Box derailleurs.
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 degreaser. We do not recommend pressure washing, strong solvents or de-greasers as they could degrade the surface coating.
