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 one is our "Compact" multi-shift variant with gear display that is fitted out with upright shift levers. Any rider that either prefers to sit in a more upright position or has smaller hands will enjoy this configuration. 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.

Derailleur hangers

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. 

Cassette Body

Q: Will Box be making cassettes compatible with XD or Microspline driver bodies?

A: At this time our cassettes are only compatible with HG style MTB 8/9/10 speed or road 11 speed driver bodies. Most hub manufacturers offer the different

Please see page 6 of our guide for notes regarding the 2 HG drivers.

Crankset compatibility

Q: Can I use X crankset with Prime 9?

A: We recommend 1 by specific cranksets to achieve proper chainline and performance. The crankset you choose will depend on your bike frame and budget.

Chainring Compatibility

Q: Can I use my standard chainring with your Prime 9 drivetrain?

A: For the best performance and chain retention we recommend you use a narrow wide 11 speed chainring. This will best match the internal geometry of our chains and provide you with the best riding experience. These are some of the brands we recommend, Wolftooth Components, Raceface, One Up Components, Absolute Black.

Box components gear ratios JUST MAKE SENSE!

Easy to install, clean shifts, and perfect ratio gaps make me hate other quality systems. Thanks box components!
