SKUBX-DT2-P9AMXW-KIT

Our Box Two tier's mission in life is to deliver performance similar to the Box One but without its exotic (and costly) features. You still get the Tri-Pack™ Clutch in our derailleur only it isn't adjustable. The cassette's 11-50T range is equally impressive but we don't cut it out of a single block of steel. The action on the shifter is just as snappy although you don't get the rigid die-cast pull lever. The chain boasts the same unique ability to mate with a wide/narrow chainring except you give up the trick DLC top coat. You're hardly shortchanging yourself with Box Two.

 

Includes Shift Housing Kit
Compatible with most 10,11, & 12-speed wide / narrow chain rings. Prime 9 chain must be used.
Not Intended for E-Bike Use

Q: What is the difference between the Wide and X-Wide?
A: The Wide cassette offers an 11-46T range while the X-Wide offers an 11-50T range.
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.

Beautiful conversion kit

Bought this to covert my worn out 3x9 to a 1x9. Super easy. Was able to get rid of my front derailleur and gain some clearance to install a wider rear tire. The rear derailleur shifts beautifully, super smooth and fast. I find that the large jump between gears is insignificant. I can climb the steepest hills and then open it up on the flats, all on the same cassette, and all with perfect, smooth shifting. Overall, I highly recommend this kit. I will be getting a second set to convert my other 3x9 bike. Thank you!

9 should be the new standard

I've been really impressed at how it has maintained shifting performance for over 6 months. There have been plenty of rock bashes along the way but it still shifts easily, will definitely buy again
