My helmet, made for mountain biking, is great...fits great, comfortable, light, cool...ON MY MOUNTAIN BIKE. When on my roadie, the chinstrap cuts a little into my throat when I'm in the drops. HUH?!?!?! Are road helmets made with the chinstrap a little forward, or do I need to adjust the strap differently? I'd rather buy a whole new helmet cuz the one I have FITS. Any ideas or suggestions???
