Since the Eggrider display is only built for 22.2mm handlebars, I designed this adapter to be able to mount it on my 31.8mm road/gravel handlebars. The holder on the handlebars is designed to be a little larger to put rubber in between so that it doesn't slip and don't damage the handlebars.

It is desgined for 15mm long M5 screws and nuts. I used self-locking nuts.
