Knowing that the base bar is the foundation of your cockpit, Zipp engineered its new Vuka Alumina Base Bar to provide the most stable, efficient, and versatile platform available from an aluminum construction. Its sleek and aerodynamic profile lets you dial in the perfect position by using a variety of clips and extensions. And, in addition to this, its design yields an incredibly durable base that provides an affordable alternative to the full carbon options. Zipp modeled the Alumina after its VukaBull, using the proven 6066 series aluminum instead of carbon fiber. Compared to the VukaBull, the Alumina weighs in around 40g heavier 250g, and it doesn't feature the same airfoil shape or drop option. However, at roughly one third of the price, and with only a minimal weight penalty, it provides you with a value oriented base bar that's still exceptionally versatile. Zipp's engineers made the Alumina as sleek as possible, incorporating internal cable routing and smooth, natural bends that form the five degree upswept hand grips. Borrowed from the VukaBull, this design promotes a natural wrist position for climbing and sprinting. The bar's wide mounting area provides an array of extension positions, allowing you to find the most optimal fit for your riding style. Zipp also designed the Alumina to be compatible with all current drivetrain systems and plug in style brake levers. It's optimized for use with the Vuka Alumina Clip, but it's also compatible with the VukaClip and most other clips on the market. The Zipp Vuka Alumina Base Bar is available in a high polish Black finish. It measures 42cm outside to outside and has a 31. 8mm clamp diameter.
