All Box stems are engineered and crafted using our Oversized Technology. As we follow the load paths down the handlebars we have focused our 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. Weve done this by moving material from low stress areas. This has greatly minimized twist and contributed to responsiveness. As the stem in mated with the handlebars we 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 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.
Key differences: In this particular model stem weve modulated the Oversized formula to emphasize pedaling stiffness. We have transferred material specifically to sectors that experience sudden stress from pulling up on the handlebars. Youll feel a difference in your acceleration. These stems are engineered for the larger-sized racers.
