Box Three P9 X-Wide Multi Shift Groupset
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!

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.
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.
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.
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.
Easy to install, enough gears to make riding easier. Great climbing gear, but with a small enough gear for decent speed on the flats
All the paper and cardboard that you sent me but there are no printed instructions on any of the surfaces. When you get a chance send me some printed instructions that I can spread out in front of me while I do the install. Do you like GPS or a real map?
Do not buy if your in Canada
I didn’t even receive the item. I needed to pay an additional shipping fee to FedEx and didn’t. So they sent back the pieces to box and I was left without a refund nor any components.Think costs me near 300$ for nothing. I wrote to box and I had no respond. If any Box support team member sees this, You still have a slight chance to have your customer back.
So far so good
Only found out about Box Components from watching Berm Peak videos, decided to give them a try for my 12yr old twins bikes. They race mountain bikes in MISCA and needed the extra climbing gears. So, we upgraded from a Shimano 1x7 to these Box 3 P9 x-wide drivetrains and haven't had any issues so far. They love the new drivetrain and how quick and easy it shifts.
Derailleur too fragile
The cassette and shifter are fine. My mistake for not pulling in the high-limit enough, but I got the derailleur inside the big gear, and then the b-limit-screw slipped off its skinny stop-platform. Then the b-limit-screw broke off, and I cannot drill it out. I think the derailleur would be a lot more durable if the b-limit stopper-platform was wider like the box-two derailleur, which I had to buy as a replacement. I advise buyers to either be gentle, or stick with the box-two derailleur.
