Engineered with proprietary Oversized Technology, the Box One Center Clamp Stem is the ultimate pro-level component for elite BMX racing. By utilizing a massive 31.8mm bar bore and augmented surface area, this top-load stem virtually eliminates handlebar deflection, ensuring every ounce of power from your pedals translates into forward momentum during gate starts. Cold-forged from 6061-T6 aluminum, the lightweight skeleton design maximizes front-end stiffness while the innovative knee-saving wedge center clamp keeps the hardware away from the rider. Paired with 1-1/8” carbon forks and an alloy frame, this track-ready stem provides the steering precision and headset stability required for high-speed motos.
