Hand sawed brass with chemically etched design.
Each bike has a different diameter head tube. This badge is currently formed to a larger size for mountain bikes, but can easily be adjusted to fit a smaller head tube for gravel or road bikes upon request. I will do my best to fit it for you, but it may require some adjustment on your end. I am happy to provide some techniques to adjust fit and adhering the badge before purchase. Send me a message if you have any questions!
