The perfect bike fit needs to blend slippery aerodynamics and a comfortable, stress free body position while optimizing control over the bike. Zipp's Vuka Carbon Extensions give you all the options needed to optimize your position and go for the win or your personal best.
Vuka Evo extensions decrease drag by starting airflow over the body sooner while keeping the arms and wrists in a comfortable, relaxed position. The Evo shape, with a 20 mm inward roll and multi-radius bend, is now available for the first time in carbon, allowing for even more complex shaping and lighter weight.
Utilizing the same Exogram technology found in SRAM RED crankarms, the Vuka Evo Carbon 70 and 110, which weigh 140 and 142 grams respectively, go beyond the capabilities of aluminum. The end is contoured to better fit the hand, as well as transition smoothly from the back of a mechanical shifter. Cable routing is fully internal. An included bezel allows the end to integrate visually and aerodynamically with SRAM RED eTap Clics and sand-paint provides excellent grip without the need for bar tape. Length is increased to 380 mm (from the 360 mm length of the Alumina Evo), further increasing fit options.
