EXTEND YOUR LEAD Zipp developed an extensive line of aluminum aerobar extensions to provide the perfect fit for any rider, regardless of size or riding position. Our Vuka Alumina Extensions offer three different bends to achieve your ideal fit. Vuka Alumina Race (175g) feature 52mm of rise The Vuka Race bend places the wrists at a more natural bend to help riders remain in their tuck to optimize aerodynamics. Vuka Alumina Evo 70 and 110 extensions are available in both a 70mm (176g) and 110mm (180g) rise. Designed to deliver improved aerodynamics by placing hands closer together and nearer to the rider’s head to start airflow over the rider sooner. Designed with input from top bike fitters, the shape of the Vuka Alumina Evo is crafted to feel as if the rider is shaking hands with the bar. This is achieved through the use of a multi-radius bend paired with a 20mm inward roll of the bar that can be adjusted to dial in fit and achieve an ideal position.
