Zipp Vuka Alumina Race Aerobar Extensions

To help every rider find their fit, we’ve created three different all-carbon extensions for the VukaAero and VukaClip™: Straight extensions will get you as low as humanly possible. Chicanes are ideal for mid-range speed and share their S-bend shape with the VukaShift. Ski Tips offer long-haul comfort.

All VukaExtensions can be shortened by almost 100 mm from their standard 335 mm length to accommodate any bike configuration including ITU-legal racing. The extensions feature internal cable routing for aerodynamics and ergonomics and weigh about 100 g per pair.

Note: VukaExtensions are not recommended or designed for other bars or clips than Zipp®’s, as the diameters may not give the correct grip.

Guidelines For Cutting The Extensions:

• The extensions are marked on the underside in 1 cm increments with half centimeter increments shown with smaller lines. A minimum of 3 cm of extension must be inserted into the VukaBullet body to avoid damaging the extensions. This means that a minimum of six marks (three large and three small) must be inserted into the bar after the bars are cut to length.
• If more than 4 cm of extension need to be removed, we recommend removing in 2-3 cm increments to avoid overcutting of the extensions.
• The extension should be wrapped in masking tape at the point where it will be cut and cut with a composite or FRP specific hacksaw blade. The masking tape will help ensure that the cut is clean and no jagged fibers lift off of the part.

Warning: Do NOT cut anything from the front end of these extensions.
