Pretty simple install of Box Two Pretty simple install of Box Two drivetrain. The included QR codes linked to 'PAGE NOT FOUND' so I had to hunt. The youtube install video was of the if-all-goes-well variety. would have like to have had a better troubleshooting guide available as i didn't get the cable tension right the first time around.

Amazing build quality! The shifter was exactly as the discribe, beautifully made can't wait to install it. Paired with a BoxOne 11 speed derailleur and BoxTwo 11-46 11 speed cassette.

Box Components stands behind their product. Box Components is a company that stands behind their product. I've used their crash replacement option with 2 derailleurs that I've destroyed, leaving me with confidence that the drivetrain I purchased will last! Tomas has helped me several times in the past and his prompt responses and professionalism instills trust with the customer. This is why I still buy from Box.

Box Prime 9 is way better than fine! Box website is easy to navigate and pricing is decent. The Prime 9 line has proven to be pretty bomb proof with little need for adjustment throughout the riding season. My Son and I run Box 2 drivetrains on our enduro and we were so impressed we spec’d out the same for our fat bikes! Just bought the Box 1 for my sons next enduro build. Thanks Box for awesome products!

Started disappointed, ended ecstatic. I bought a box 3 Prime 9 drivetrain and unfortunately the derailleur snapped. (I didn’t know that the 3 series was for lighter riding) I emailed the Box team for a warranty claim and Tomas Ovalle explained how the 3 prime 9 is for more beginner level riding. He then offered a free replacement, or %50 off a drivetrain of my choosing! Obviously I chose the discount. I now have a more durable drivetrain for a super cheap price. Box - whatever you’re paying Tomas, you should pay him more. That dude was awesome.
