The new VukaSprint carbon drop bar adapts the VukaBulls advanced airfoil top section to be more aerodynamic at the angles most commonly found in a drop bar setup. Internal cable routing and a sculpted top section provide comfortable hand positioning, while the broad profile and stiff carbon fiber layup yield a responsive ride quality. Even so, the VukaSprint weighs just 235 g 44 cm. The VukaSprint is available in Short Shallow and Traditional Bend drop shapes in 40 to 46 cm widths. This product is UCI compliant. Note: The VukaSprint is compatible with Ultegra Di2 and DuraAce 9000 Di2 components but is not compatible with earlier electronic shifting systems.
