BOX One Oversized Front Load Stem

Oversized Technology increases the surface area at the connection point between your stem and handlebars. This extra contact minimizes twisting and flex, which translates into more direct power transfer and a stiffer feel when you pull up on the bars.

This stem is designed for a 31.8mm handlebar clamp diameter and a 1-1/8-inch steerer tube. Please verify these measurements on your current setup before purchasing, as it will not fit standard or oversized bars outside of these specific dimensions.

While it is compatible with many bikes, it is specifically engineered for larger-sized racers who need extra stiffness and responsiveness. If you are a smaller rider or prioritize weight savings over maximum rigidity, you might find other options more suitable.

The weight depends on the length you choose. The 48mm version weighs 280g, while the 53mm version weighs 290g.

Yes, it includes high-strength chromoly clamping bolts. The stem is cold-forged from 6061-T6 aluminum, ensuring it is durable enough to handle the stress of aggressive riding.
