I just added a Cateye computer to my video making toolbox. Below is a short sample video of the results. You will need drop bars, a wide angle camera mounted to the bars, an
ORIGIN8 FRAME/FORK EYELET STUB, a stack of small washers, a few nuts, a longer 5mm or similar diameter screw, and a rubber coated strap commonly used to install racks on bikes without braze-on attachments.
