Zipp’s Vuka Extensions are made of ultralight, stiff carbon and come in different bends so that you can find the model that optimizes your aero position and maximizes your speed. The Straight extensions place you as low as possible, while the Race and Ski-Tip models have more bend for your wrists. Then, for a seamless junction between your shifters and the extensions, the Race Vuka Shift has built-in mounts that let you screw your shifters directly to the extensions. They accept Zipp’s R2C Aero shifters and SRAM's 900 TT and 500 TT shifters. All the extensions have internal cable routing and gradations to make adjustments easy.

Zipp developed an extensive line of aluminum aerobar extensions to provide the perfect fit for any rider, regardless of size or riding position. Vuka Alumina Extensions offer three different bends to achieve your ideal fit. - Vuka Alumina Ski-Tip offers a hand position for long-haul comfort and speed. 185 grams. - Vuka Alumina Race features 52mm of rise and places the wrists at a more natural bend to help riders remain in their tuck to optimize aerodynamics. 175 grams. - Vuka Alumina Evo are available in both a 70mm (176g) and 110mm (180g) rise. Designed to deliver improved aerodynamics by placing hands closer together to start airflow over the rider sooner, 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.
