Box One Top Load Stem

The Oversized Technology increases the surface area where the stem meets the handlebar. This creates a more rigid connection that reduces flex and twist, resulting in more direct steering and efficient power transfer when you're pushing hard.

This stem is specifically engineered for BMX bikes with a 1-1/8-inch steerer tube and 31.8mm handlebars. It is not designed for standard mountain or road bike setups, so please verify your bike's measurements before purchasing.

Not at all. The top-load design is built for easy handlebar installation and removal, allowing you to swap bars or adjust your setup without a complicated process.

Forging the aluminum allows for a strong, durable structure while keeping the weight down. By strategically removing material from low-stress areas, the design maintains high stiffness where you need it most without adding unnecessary bulk.

A 0-degree angle provides a neutral rise, which helps maintain a consistent handlebar height. This is a common preference for BMX racers who want a predictable, stable feel in the cockpit.
