Cork Bar end plugs suitable for handlebars with inside diameter of 17 / 18mm.
Like the bottle corks, these caps must enter under pressure, to prevent them from falling at the first impact.
Another advantage of the cork, is that if the plugs are too wide you can always trim them with some cuts to better adapt to the inner bar (for example in the lace path, for the leather grips), and if they are too narrow you may have to trapp the ends of the laces in the gap. Double if necessary.
Sold as a pair.
