Remember kids... always wear a helmet. (The almighty bikeradar helmet thread)

Whilst they don't have bb dates trail centres etc are obliged by insurers to replace every 2 years from d.o.m. I was led to believe. If buying I'd prefer a more recent one, tho still quite happy rocking my 3yr+ one at the mo too.

I wonder if the two year rule is based on research provided to the insurers by the marketing department rather than the r&d teams.
