By integrating the bar-end shifter boss into Zipp’s chicane aerobar extension,
we've created something that weighs less and improves ergonomics at the same
This full-carbon, aero extension saves up to 80g by eliminating the need for the
expansion bolts required to install standard bar end shifters. As a result,
there's No need for a straight section at the end of the extension, which allows
the VukaShift to move the shift levers 30mm closer to your hands and easing
strain on your wrists.
At around 60g each, the VukaShift is simply a better system than what came
before. SRAM and Shimano versions available.
Guidelines For Cutting 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.

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.
