Zipp Vuka Stealth Handlebar 
 The very best in aero and adjust ability the new Zipp Vuka Stealth takes the what Zipp learned form the original Vuka bar.
The Vuka Stealth breaks barriers for what’s possible with an integrated aero system. It’s sleek, clean and almost endlessly adjustable.
Amazingly the Vuka Stealth provides a stunning 1,920 fit options. Dial in your position for comfort and efficiency while optimizing your body’s wind drag.
What does that mean for on-the-bike performance? Pro triathlete Jordan Rapp put the Vuka Stealth on his bike and just six days later won the Leadman Epic 250 Triathlon, with its grueling 223 km cycling leg. “I never really noticed the bar, which is probably the highest compliment I can think of,” Rapp said. “I basically forgot it was there, which was awesome.”
The Vuka Stealth integrates the stem, basebar and mounting hardware into a single streamlined aero system. The base bar uses a truncated airfoil shape that maximizes aerodynamic efficiency while maintaining the UCI’s 3:1 aspect ratio requirement. The basebar’s Rapid Routing cable exits are positioned for easy installation of brake cables.
The Vuka Stealth is available in three separate stem lengths – Short, Medium or Long. You pick one. Each size also includes stem-length spacer to increase stem length by an additional 10mm. That provides a total of 50mm of stem-length variation. The effective stem angle results in no rise, or what would traditionally be referred to as a -17° stem.
To achieve an optimal fit, the bar offers scores of additional adjustments to its “stack” (vertical measurements) and “reach” (horizontal measurements) as well as options for the pad width and position and extension width and length.
The Vuka Stealth is crafted from unidirectional carbon fiber and uses titanium and aluminum hardware. It is made with the industry standard 22.2 mm extension clamp diameter for maximum versatility, making it compatible with Zipp’s Vuka Extensions (Race, Straight, Ski-tip or Race Vuka Shift styles) as well as most extensions on the market. Extensions are sold separately.
The Medium Vuka Stealth with Zipp Vuka Race carbon extensions weighs 820 grams. Compatible with all current drive-train systems and all plug-in style brake levers.
Sizes (out-out) 42cm
Integrated stem Short, Medium or Long. The nominal reach of the short bar is 2mm, the medium is 22mm and the long is 42mm and in each case you get an additional spacer that allows 10mm of forward adjustment.
Stem length is not as important as in traditional bar/stem set ups as the arm pad adjustment if a bigger factor.
Stem-length spacer adds 10mm to any of those sizes
Steerer tube diameter 1-1/8"
Weight 820g (Medium stem length with Zipp Vuka Race carbon extensions).
