Our conical shaped Spire Bar End Plugs are the perfect addition to any track racers, triathletes, or time trialists gear bag. Each plug, when inserted into the end tip of a handlebar, creates more aerodynamic wind flow over and under any track bar or bar extension.
                
                
                The toughened 3D print material creates a strengthened yet smooth structure. The Spire Plug is finished in ceramic coating. The plug snugly fits into most track handlebars and is secured by two O-ring locks (removable.) All of our 3d printed parts are made in our Tennessee, USA facility. Spire plugs are sold as pairs.
