All Box stems are engineered and crafted using ‘Oversized’ Technology. As Box followed the load paths down the handlebars they have focused attention on the stem-to-bar interface. Since the Oversized handlebars have an increased wall thickness and tube diameter in this sector they reciprocated with an augmented stem interface with greater surface area. They achieved this by moving material from low stress areas. This has greatly minimized twist and contributed to responsiveness. As the stem is mated with the handlebars it increased pedaling 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.
Key differences: This particular model stem pushes the ‘Oversized’ Technology to the extreme as it maximizes the shift of material from low stress zones to the Oversized interface. These stems are engineered for the smaller-sized racers.
