As an MA scrutineer, we have a rule book that outlines what is a safe helmet and which is not.
The easiest way to see if a helmet will pass scrutinizing is by – name, approved sticker and the condition of the helmet. eg; cracks or deep scatters will not pass.
Accessorizes to helmets like visors – shield or sun, goggles & go pros are in my opinion fine. I would not knock a helmet back with these accessories.
The problem with the boys in pink, is that they to have a rule book, but it is only a guild line.
We will have to wait till it is tested in a court of law. When it is, and I hope it is, as I think he has a good chance of winning, please post the result.
O. myself, I have a go pro chess plate for riding in the dirt, as I’ve seen heaps helmet go pros GO. Trees love helmet go pros.
When on a road bike I would have a helmet cam.
