If you’re a fan of BMX racing, then you’re already familiar with Box Components. They produce a range of products for little bikes and have recently branched out into the mountain bike segment. Their MTB products include handlebars, headsets, wheels, and small parts.
Over the past few years, they’ve also been developing a new drivetrain. Considering the market dominance of Shimano and SRAM, not to mention their treasure trove of patents, it’s a bold move. So what makes the Box drivetrain special? It uses a single lever shifter.
As the short video demonstrates, you can downshift using the familiar sweeping motion with your thumb, or upshift by pushing the paddle inwards.
The derailleur is also a Box designed unit. Like any modern derailleur, it uses a clutch assembly to help with chain retention. What sets it apart is the pivot technology. If you hit the rear, let’s say on a rock, the cable stay can pivot. This helps prevent the derailleur and hanger from snapping.
The drivetrain will initially be available in two build kits. The Box One system is an XT or GX level kit, while the Box Two version is equivalent to SLX. At launch, they will offer an 11-46 11-speed cassette that uses a Shimano freehub. You could also use a SRAM cassette if you prefer.
Retail for the Box One shifter is $75. The rear derailleur retails for $180. The Box One 11-46 Cassette isn’t quite ready for production, but the $100 Box Two will be shipping by December.
