Box Three Prime 9 X-Wide Groupset (9 Speed) (Single Shift) (12-50T), While most companies now days are expanding their drivetrains upwards of 13 speeds, Box believes that more is not necessarily better. The Idea behind the 9-speed drivetrain is to keep things simple while receiving the same gear range in a more efficient package; resulting in less shifting error, which produces a more user friendly experience.
