Box One Oversized 31.8 Center Clamp Stem – Black 60mm 1-1/8″

All Box stems are engineered and crafted using their Oversized Technology.

As they follow the load paths down the handlebars we have focused their attention on the stem-to-bar interface. Since the Oversized handlebars have an increased wall thickness and tube diameter in this sector they have reciprocated with an augmented stem interface with greater surface area.

By moving material from low stress areas. This has greatly minimized twist and contributed to responsiveness. As the stem in mated with the handlebars they have contributed to 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.

This particular model stem not only shifts material from low stress zones to the Oversized interface, but also moves the clamp to the center and out of your knee’s way. These stems are engineered for the larger-sized racers.
