I bought my bike couple months from this dealership, and I also bought some gear from them as well. I know I probably should have checked but the excitement of a bike got the best of me. Anyway so I was looking at my helmet yesterday cus it’s a 2x and it fits super loose now. I see a tag that says March 2013. Buddy of mine tells me they should have sold me that helmet do it expiring. I’ve read things saying 5-7 years is manufactures suggestion on replacing. So I called the shop n told them and the guy told me it’s fine. That that 5-7 year replacement is meant if I’m racing and not for regular street use. Any truth to this? Do I need to buy a new helmet aside from the fact that it’s to big?
