The Box One Oversized Stem utilizes proprietary Oversized Technology to maximize 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 high-torque gate starts. Cold-forged from 6061-T6 aluminum, this top-load stem features a massive 31.8mm bar bore designed specifically for oversized chromoly bars and carbon bars. Engineered for 1-1/8” steerer tube forks and alloy frames, the tailored geometry allows for easy handlebar removal while maintaining track-ready durability for high-speed motos and precise steering control.
