The Box One Oversized Stem utilizes proprietary Oversized Technology to redefine front-end stiffness for elite BMX racing. By increasing the stem-to-bar surface area, this pro-level component eliminates handlebar deflection, ensuring maximum power transfer during gate starts and high-torque pedaling. Cold-forged from 6061-T6 aluminum, this top-load stem features a massive 31.8mm bar bore designed specifically for oversized chromoly or carbon bars. Engineered to mount perfectly to 1-1/8” steerer tube forks, it enhances steering responsiveness on any alloy frame. The tailored geometry allows for easy handlebar maintenance while providing the track-ready strength needed for the world's fastest motos.
