This is bicycle handle bar. I focused most on how to make it as simple as possible. My idea is to use a mount that is made of rubber. On the one side a screw goes through all and in the end a nut bolts on. On the mount there is a special cut so that the nut fixes in it and as we screw it on, the nut presses the mount back, compressing it, and causing it to expand in diameter (as its length reduces). I've also focused on installing it without needing any special tools. We put on tha mount inside the bicycle tube and then put the bolt in the special cut on the cap and bolt it in bu turning the cap with bear hands. The logo plate can be glued on the cap, but still you can remove the cap without having to take off the plate. By turning in with your hands..

Hope you like it:)
