Parents got me a cool metal bell for Christmas, but the metal bracket it came with was designed for super thin handlebars, not the center section of a large clamp diameter bar. Came up with a pretty slick MacGyver mounting solution, using the bracket for one of those cheap white reflectors everyone has laying around that come on new bikes but get removed right away. Bent the top half of the metal bracket to sit flush against where the reflector mounted to its bracket, then screwed the bell on that metal half, onto the plastic bracket that fits. Bonus, it elevates the bell housing enough to clear my hand better, and leave my little backup LED flasher light mounted to the bars under it. Also easier to ring elevated a bit like this. Good way to maximize usable area in the center of the bars for mounting stuff...
