Zipp Vuka Clip with Carbon Race Extensions Description: The Zipp Vuka Clip with Carbon Race Extensions are a highly adjustable set of clip-on aerobar extensions that are designed to add comfort in addition to improving aerodynamics. The shaping of the carbon fiber Vuka Race extensions has been designed to reduce stress on a rider's wrist and will accept most plug-in, TT style shifters. Stiff aluminum handlebar clamps provide a secure connection and rock-solid foundation for the extensions. Finally, highly adjustable arm rest cradles allow a cyclist to dial in their aero tuck for maximum performance and will make that positioning comfortable enough to stay there while flying through the race course all of the way to the finish line. Note: Not all handlebars are designed to have aerobars attached to them. Please consult the owner's manual or the manufacturer of the handlebars to make sure those base handlebars can accept the additional pressure that aerobars put on them.
