Box One BMX Cranksets – Oversized Technology™ for Maximum Power
All Box One and Two Cranksets are engineered using Oversized Technology™, built around one goal: deliver every watt of power straight to the rear wheel. By enlarging the spindle and crank arm interfaces, Box cranks dramatically reduce lateral deflection at the bottom bracket, giving riders unmatched pedaling stiffness, instant acceleration, and maximum efficiency.
Instead of adding unnecessary weight, Box engineers reinforced only the zones of high stress while removing material from unloaded sections. The result is a set of cranks that feel incredibly responsive under power while staying lightweight and race-ready. Riders benefit from less wasted energy and faster elapsed times, making Box cranks a true performance upgrade.
Box One M30 Crankset
The Box One M30 Crankset is designed with the same obsession for stiffness and efficiency as its big brother, the Box One M30, but scaled for smaller riders. Built with a 30mm spindle and hollow-forged crank arms, the M30 provides extreme stiffness without unnecessary bulk. Stabilizer rings were removed from the spider and excess material shaved from its legs, ensuring that smaller riders get the perfect balance of stiffness, weight savings, and responsiveness.
