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.
