Box components Box Two Center Clamp Stem BMX Headset

Box Two Center Clamp stems are cold forged from the highest quality 6061-T6 aluminum available. Featuring an open skeletal design and a dual mid-bolt wedge mounting system they are lightweight yet maintain a very high level of strength. By removing the rear pinch bolts and moving the mounting bolts to the middle of the stem Box reduced the weight and size and eliminated a serious hazard to the rider`s knees
