Zipp Speed Weaponry has released details of its first shifting component.
The VukaR2C – ‘Return to Centre’ – aero shifter is the latest from the Speed Weaponry stable, combining high performance aerodynamics with top-notch ergonomics.
Weighing 180g per pair, the aerodynamic plug-in shifter shaves up to six seconds over 40km compared to a traditional TT lever, according to Zipp. Set at the natural angle for the rider’s hand position, the shifter’s return-to-centre actuation resets the lever to the original angle following each shift – keeping the rider as low and comfortable as possible.
Tested in Kona in 2008, the VukaR2C is compatible with all aero bars and optimised for Zipp’s VukaShift extensions, eliminating the shifter’s expansion bolt and allowing riders to attach the mechanism directly to the aero bar extension. SRAM and Shimano versions are also available.
The VukaR2C has already been announced as the RZR at Eurobike earlier this year. The name change is down to bringing the product closer to Zipp's Vuka family of aerobars, as well as SRAM shift lever technology, apparently.
