If it's a Bell helmet, you're good. I've crash-tested two of them. Lots of road rash in both cases, but my noggin was fine. Bell will replace any of their helmets, regardless of the model or when you bought it, for a flat price of $35. Incidentally, if your helmet hits the pavement or any other solid surface, replace it whether or not there is any visible damage. It's a good idea to buy a new helmet every 3-4 years anyway, as the EPS foam starts to deteriorate with time.
