All Box handlebars are engineered and crafted using our Oversized Technology. Handlebars have a dual purpose as they contribute to both steering and pedaling stiffness. By strategically varying wall thicknesses and tube diameters, we have moved material from 3 low-stress areas to zones of high load. This has greatly minimized twists and contributed to responsiveness. Concurrently we have 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 deflection and the consequences can lead to 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 handlebar is tailored for medium-sized racers so we decided to use hardened aluminum alloy to reduce unnecessary mass. FEATURES - Oversized™ Technology - Hardened Aluminum - To Reduce Unnecessary Mass for Medium-Sized Racers - Massive Clamp Interface for Steering Stiffness - Variable Wall Thickness to Reduce Weight
