glad to hear she is ok. I use a HJC SPX in flat black. So using the same as you.
It did do the job she was badly injured but lived... just never expected to see it crack like that. Being back into the sport again after so many years, I try to buy the best when it comes to my safety, thats why I ask what everyone is wearing on there noggin because if there is something better than I want to know. These stores only sell you the best of what they carry not the best on the market.I use Bell helmets, always have. Have always used the Moto 7, but looks like they no longer make those, so my next helmet will be a Moto 8.
So, do you think the helmet should not have cracked? Depending on how she hit the ground and the force she hit with, this could very well happen with any helmet. Looks to me the helmet did its job. Even if it did not crack, I would still recomend it gets replaced. Once a helmet gets hit, the foam is slightly compressed, meaning that it will not offer the same amount of protection on the next hit. I have even been told that if you drop your helmet on a hard surface you should replace it. Yes, helmets are expensive, but what does your life cost?
