Hi there!  I'm a newbie both to riding and this forum.  I recently bought my first helmet, it's a Specialized.  The problem I'm having is that you have to pinch the buckle to take it off and I have torn tendons in both of my thumbs!  Does anyone know of some kind of adapter so that I can change it to one of those buckles that you just push on the center to release it?  I hate to tear apart a new helmet to change out straps. Many thanks, Julie
