The Box Two 35mm bottom bracket is engineered with Oversized Technology and developed in concert with Box crank sets to maximize power delivery and pedaling stiffness. By oversizing the bottom bracket and enlarging the spindle and crank-arm interfaces, it makes room for larger bearings and a vast increase in contact area for reduced lateral deflection. The result is more efficient power transfer and instant acceleration response.
