The info is available on the Giro website. I've taken screen shots of the relevant info and will include them here.
I found this by going to the Giro website at http://www.giro.com/main.html. I selected Giro info (on the left), then FAQ.
Wait - looking at these as attachments is a pain in the butt. I'm going to go ahead and type the info here. (The quote below was copied directly from the Giro web site as it existed on September 1, 2006.)DOES GIRO HAVE A CRASH REPLACEMENT PROGRAM?
