Zipp VukaShift Extensions

Instead of bolting the shifter onto an assembly that plugs into the aero extension, why not just bolt the shifter onto the extension itself? That’s the simple idea behind the VukaShift. This designs saves up to 80 grams by eliminating the use of expansion bolts inside the extensions. By moving the shift levers 30mm closer to your hands, the VukaShift eases wrist strain and keeps your hands in the fastest aero position as you shift into the 11. The VukaShift extensions use Zipps chicane shape and weigh approximately 120 grams per pair. Note: The VukaShift is currently available for "standard" bar-end shifters. A new version compatible with the new Zipp VukaR2C shifter will be available in mid-January 2010.- Call for Information Guidelines For Cutting The Extensions The extensions are marked on the underside in 1cm increments with half centimeter increments shown with smaller lines. A minimum of 3cm of extension must be inserted into the VukaBullet body to avoid damaging the extensions. This means that a minimum of 6 marks (3 large and 3 small) must be inserted into the bar after the bars are cut to length. If more than 4cm of extension need to be removed, we recommend removing in 2-3cm 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 Shifters. Note: Bar End Shifters not included.
