Box Three P9 Wide Multi Shift Groupset
SKUBX-DT3-P9AMW-KIT
Our Box Three tier delivers many of the same capabilities of its more famous siblings yet it's built upon a simpler platform. Cassettes are accessible at 11-46T or 11-50T and fashioned with steel spiders. The derailleur exploits our Limited Slip clutch technology without the Tri-pack features. Shift easily with a comparable mechanism, although you'll forgo the hinged clamp and die-cast structure. And lastly, string it all together with a Prime 9 chain but without extravagant coatings. If you're looking to bring your 2/3 by bike into the 21st century, then level up with this group!

FAQ
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.

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.

Great option for older frame
This was the best option for an older 135mm hub and super narrow chainline. Couldn't have revived my 2005 ellsworth specialist without it. Highly recommend.

budget
I ended up getting this groupset because there was so much was out of stock on other brands, and thank goodness everything else was out of stock , for such a inexpensive set it has worked all summer with out any issues . crisp shifts very easy setup and no issues even with the abuse i put my gear through. we ride single track that is very techie and some fast down hill at a bike park near us . worked great for eveything i needed ....... no more looking at another brand im coming back to box for my next groupset !

Loved it
It was an amazing product my one critic is it feels like it needs to be tuned a lot but other then that I would say 5 stars.
