I used a good idea someonelse posted several years ago, being a machinist by trade I found a small 10mm Id bearing and bored out 2 different #40 sprockets - a 12 and a 13 tooth and prressed a bearing into them. With changing of rear drive sprockets I can select whichever diameter I need and bolt it on. It works great as I use a 10mm bolt to assemble it on the bracket
