One Top Load Overszied 31.8mm BMX Handlebar Stem

Size

All Box One top load stems are engineered and crafted using Oversized Technology. As we follow the load paths down the handlebars and have focused attention on the stem-to-bar interface.

Since the Oversized handlebars have an increased wall thickness and tube diameter in this sector, we have reciprocated with an augmented stem interface with greater surface area. By moving material from low-stress areas. This has greatly minimised twist and contributed to responsiveness. As the stem is mated with the handlebars, we have contributed to increased pedalling stiffness by providing a backstop to the 'lifting' phenomenon. There is no point pushing hard on your pedals if you can’t pull up on your handlebars and deliver that power. Power can easily be lost to handlebar-to-stem deflection and the consequences can be poor power delivery and steering control. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency.

This particular model stem not only shifts material from low-stress zones to the Oversized interface but also provides rigidity through the side skirt design. Using a reverse development process for the delta stem, the structure was created from the outside-in vs. the traditional inside-out method. These stems are engineered for larger-sized, stronger racers.
