Vuka Alumina Base Bar Every high-performance aero-cockpit begins with a great base bar. The Vuka Alumina, crafted from 6066 series aluminum, offers superior aerodynamics and ergonomics at an affordable price. The Vuka Alumina base bar delivers on a big challenge given to our engineers – create a high-performance aluminum base bar that’s modeled after Zipp’s standard-setting carbon VukaBull base bar. The Vuka Alumina base bar is sleek with clean internal cable routing for easy installation. Handgrips are angled upward by 5 degrees for a natural wrist position when climbing or sprinting. The bar’s mounting area is wide to allow for an array of positions to accommodate many riding styles and body types. The Vuka Alumina is compatible with all current drive-train systems and all plug-in style brake levers. It’s optimized for use with the Vuka Alumina Clip but is compatible with most clips on the market. The Vuka Alumina is lightweight at 250 grams has a 40cm (center-to-center) width and a 31.8mm clamp diameter. Its Bead Blast Black finish and laser-etched graphics mean the bar looks as smooth as it performs.
