I just got back from riding this afternoon and I got 2 hairline cracks in my helmet from taking a shot to the mouth guard from a baseball sized rock. I'm sure I know the answer to this, but should I chuck it? It was a VERY nice Moto 6 (not SL) and was $369...I'm very bummed out about it. I definitely won't spend that again to replace it.
Also bobs cycle supply was selling Arai helmets for half their retail value. I got one about 8 months ago. You have to telephone them and specifically ask about them.
