Zipp developed an extensive line of aluminum aerobar extensions to provide the perfect fit for any rider, regardless of size or riding position. Vuka extensions are 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. - Clean internal cable routing for easy installation - Length: 360mm
