Box Three Prime 9 Mountain Bike Groupset Kit – Complete Drivetrain Solution

Box’s innovative Prime 9 Technology is grounded in the principle that less can be more, delivering expansive range without added complexity. Suitable for eBike and mountain biking applications, it simplifies the riding experience. The Prime 9 system provides a comparable range to a 12-speed drivetrain but with fewer gears to navigate, thereby enhancing simplicity. Key advantages include a reduction in the number of parts, a decrease in overall weight, and an increase in durability. By minimizing the chain angle in the lower gears, Prime 9 drivetrains facilitate a straighter chain alignment across all gears, thereby extending the lifespan of both the chain and cassette. The 2-piece multi-shift pull lever enables riders to shift up to 3 gears at once. Furthermore, the Prime 9 chain is designed to be compatible with modern narrow/wide chainrings, resists elongation over time, and reduces wear on both the cassette and chainring.
