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 œliftingâ phenomenon. There is no point pushing hard on your pedals if you cant 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 Boxs other Oversized components, youll experience heightened responsiveness and reduced latency.
