BOX developed ultra wide range 9 speed drivetrains for E-Bikes. This lead to BOX components going back to the future with Prime 9 technology. A drivetrain philosophy that borrows simplicity from the past and brings it into the modern format. The results are durable, simple, yet high performing shifting systems that have caught the industry by surprise chasing 12speed.
