Description
Using the proven shape of Zipp’s Vuka Evo bars, the Electronic Controller Vuka Shift AXS 90 Carbon Extensions not only provide a lightweight, comfortable and aerodynamic position but also house the AXS system. This means that these extensions replace the SRAM BlipBox that is required to use RED or Force AXS shifters and derailleurs on a TT or triathlon bike, tidying up the cable routing and cleaning up the front end of the bike.
Blips for the end of the extensions are pre-installed and Clics for the basebar are included so that shifting can be actuated from either hand position.
As the rear of the extensions is a standard 22.2mm, these will fit most basebars / risers on the market so are an easy retrofit.
