Just bought an Airoh Rock helmet, not the cheapest, but I wanted to get a decent one, carbon Kevlar shell etc.

It does not have an ACU gold sticker. Did a bit of surfing, and one online shop is saying it has silver approval

Will I be able to use it in competitive events?

Apologies, probably a common question, but couldn't get the search feature to work on here.

Thanks in advance

I think I have found my own answer;

"HELMET STAMPS

Helmets are examined at scrutineering in order to assess wear and tear, general deterioration and to ensure that an ACU Approval Stamp is displayed. The only stamp eligible for competition use, except trials is displayed below."

Cue picures of Gold and Silver stamps

So looks like you do not need an ACU stamp for trials.

Hi Uncle Dave

I confirm for you that a Gold or Silver ACU stamp is not a requirement for a trials helmet
