The Box Two Oversized External Bottom Bracket (30mm) is designed to get more “direct power” and eliminate some of the standard drivetrain loss. During the creation of Box’s bottom brackets they emphasized Power delivery AKA pedaling stiffness. To reduce lateral deflection Box chose to oversize the bottom bracket and therefore subsequently enlarged the spindle and the crank arm’s interfaces. This made room for larger bearing rings contributing to a vast increase in contact area. Box removed material where it wasn’t crucial and applied that to high stress areas to maintain its weight yet add more durability. Not only are you going to be more efficient with power delivery, but you’ll also feel the instant response of acceleration.
