BX-DT4-08AMW-KIT

DESCRIPTION

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.

FEATURES
  • Our 8 is Enough Drivetrain
  • For Light / Medium Terrain
  • Install at Home with Some Simple Bike Tools and Our Easy to Follow Video
  • Limited Slip Clutch™
  • Ultra-Wide Ratio with Consistent Progression
  • Compatible with Traditional Derailleur Hangers (Non Direct-Mount)
  • Cassette Compatible with HG Freehub Bodies

IMPORTANT NOTES

FAQ

Groupset

Please refer to the installation video available at https://boxcomponents.com/collections/support

Derailleur

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.

Very decent

For the price you can’t go wrong. If you are upgrading you driveline from a 3x and don’t want to break the bank, this is definitely for you. Shifters aren’t as precise as my sram but for the money I can’t complain at all. Full marks Box! Good job.

Awesome groupset for the price

I love the price and simplicity of setting up the shifter and once you set up never have to touch it again!! Sadly I did snap it while I was downhilling but thankfully the warranty on these are great and was replaced no questions asked thanks for being an awesome company Box!!

Wow!

This is a **** of a 1x upgrade for under $200! I'm relatively handy and comfortable with wrenching on things, but totally new to really tinkering with bikes. After reading Box's support materials and watching their Youtube video and a few others, installation of this groupset was a breeze. It only took a couple of hours and I know that I could have completed the installation a lot quicker if I had to. Super impressed with the quality of the components. Everything seems built to last and the performance has been great -- crisp gear changes, quiet ride, superb chain tension. Lastly, Box's customer service and support is, in a word, outstanding. They were more than happy to answer my newbie questions and provide guidance. Totally impressed across the board -- thank you!

Budget mtb extravaganza!

I recently purchased a project bike for my family. It had a really decent 3x9 system installed, but lacked the needed range for climbing our local trails. So researched this kit and realized it had the same range as my last 1x11 I had in a high end mtb I rode. Installing was easy, kit is high quality, came with a new chain! Looks good, performs well, even on my janky hub still never missed a beat. Worth every penny! Great budget option into the 1x world. Fyi the clutch is so strong this old bike is now quiet and a breeze to pedal

Super strong tri-action clutch derailleur

The clutch action of the rear derailleur is fantastic. The force required to shift is much more than I'm used too - compared to shimano/sram. The engagement is strong and I am enjoying it much more then other brands. I definitely consider Box components an upgrade. I was going back and forth between 8 or 9 speed. I ended up going for the 8 speed setup. The range of gear ratios is plenty for any riding style in my opinion. I am very pleased. The quality of this groupset is very good and at this price point it is a no-brainer. The groupset includes a master link which was not mentioned in the description so I ordered 1. Upon arrival of the package I ended up with 2 master links. Turns out the optional Box narrow wide chain ring is not compatible with a master link so be aware of this. Despite the master link incompatibility, I highly recommend this groupset.
