Zipp Vuka Stealth Integrated Aero Bars
$1,006.00
Send a shiver down the spine of your competition with Zipp’s integrated Vuka Stealth. This ultra-stiff, fully carbon cockpit is even faster than it looks. With almost 2,000 fit options, dialing in your perfect position is finally possible, allowing you to get more aero, produce more power, and conserve more energy. Choose from three stem lengths, each of which includes spacers to increase stem length by an additional 10mm. You can make additional adjustments to the stack, reach, and pad width and position, as well as extension width and length (extensions are sold separately). The base bar's truncated airfoil reduces drag and meets all UCI regulations, while the grips are roughened so you don't need tape. Zipp's Rapid Routing makes running the cables inside the bars easy so everything is tight, orderly, and above all—fast.
Vision Metron TFA Aerobars
$999.99
Vision’s TFA Aerobars were rigorously tested with sophisticated computer simulation and extensive wind-tunnel testing to create the ultimate, class-leading front end, and the fastest aerobars Vision has ever produced (3% lower drag than any other Vision aerobars). For maximum lightness and stiffness, this system is made of carbon throughout with a wing-like carbon base bar, an integrated carbon stem and blade-like carbon brake levers. Plus, it's completely adjustable to dial in your ultimate aero tuck with fore/aft and width arm-rest positioning, a riser kit and extensions that can be placed wherever you need them and cut to length, too. You also get internal cable routing for more drag reduction, ergonomic gripping areas for comfort and you can even adjust the stem angle for different front end geometries.
FSA Plasma Integrated Compact Handlebar
$654.00
The FSA Plasma combines a compact bar and stem into a single carbon/Kevlar monococque construction, eliminating the stem clamp for reduced weight and improved stiffness. The dramatically flattened top section is both aerodynamic and ergonomic, as well as visually distinctive. Cables are routed internally via ports adjacent to the shifters. These ports and internal cable tunnel have been enlarged to accommodate the connectors on electronic shifting systems. FSA road handlebars are measured from center to center of the drops. Due to the outward angle of the drops, FSA road handlebars will be narrower in the brake hoods than the drops. - Bar Drop: 125mm - Drop Bend Style: Compact - Bar Reach: 80mm - Flare: 2° - Material: Carbon
