Zipp Vuka Alumina Evo Extensions

The Zipp Vuka Alumina Evo extensions use a standard 22.2mm clamp diameter. As long as your existing aero bar clamps are designed for this industry-standard diameter, they will be compatible.

Yes, these extensions are fully compatible with both electronic and mechanical plug-style shifters. The internal cable routing is designed to accommodate the wiring for electronic systems while keeping your cockpit clean.

The multi-radius bend is engineered to position your hands closer together and nearer to your head. This specific geometry helps smooth airflow over your body, reducing drag and improving your overall aerodynamic profile.

These extensions provide extensive rotational and length adjustability. This allows you to fine-tune the angle and reach to match your specific biomechanics, helping you balance comfort with power output.

While carbon fiber is generally lighter, these are constructed from 6066 aluminum alloy, which offers a robust balance of durability and weight. They are an excellent choice if you prioritize structural reliability and adjustability over the absolute lowest possible weight.
