Here's a question for those in the know. Per the GCR today we have to have a helmet with Snell2005 or newer. As I understand it the more generic rule is it is acceptable to have the newest SNELL or one previous.

As we approach 2015, I am assuming I will have to retire my 2005 helmet, but the question is does the 2015 take effect at the beginning of the year, the end of the year or somewhere in between? That is to say if the SNELL 2015 helmets aren't available yet for my first race will I have to upgrade to a 2010, or, use my 2005, get the annual sticker, and wait until the 2015's are readily available?
