I love to tinker and build my own stuff. Sometimes it works out, sometimes not. But this time, I think I've got a good one. First off, I don't like grime or sticky residue on my bike. It must remain clean. So sticking the bike number for races onto the frame eeks me out, as I know I'll be cleaning it off later. Not any more.
Using the rear reflector mount and some mid stiffness plastic, I was able to create this beauty. I drilled some holes in the plastic to reduce weight. Overall it's very light at 20 grams and does the job perfectly. Heck, it didn't move when I was doing 80 mph going home with the bike mounted on my truck.
