My box review Customer service is super helpful. I've outfitted four 29 inch BMX bikes with box components brakes, levers, cables, stems. It's a high quality BMX racing product and it's super light.

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.

Prime9 wins for durability and reliability Well packaged and delivered on time. The components are well made and durable. I prefer the Prime9 for the increased durability and wear resistance. I had this setup on my bike for about 5 years without issue. Highly recommend if you want things to work when it's time to ride.

Outstanding Customer Service - Great Products I really appreciate the great customer service I have received whenever I have had any questions. There is a lot I don't know and when deciding on products it helps to have a partner in Box to help me make the right choices. I have never been disappointed by any of the products I have ordered.

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.
