I am trying to fit lights powered from SON dynamo hub to a bike with OS (Oversized 3.18) handlebars. These type of lights have a place for a screw but no bracket. I bought a bracket that should have worked but it does not fit on the OS handlebars (see
http://www.m-gineering.nl/sindexg.htm, click on SON, click on fitting). I'm sure I can't be the first person to hit this problem. However, the black arts of Dynamo configuration don't seem to be well catered for in standard bike shops. Can anyone out there suggest a bracket that I can use with OS bars to fit my dynamo driven lights?
