"The T2 Carbon is t.h.e.'s new top-of-the-line carbon-fiber helmet. At just over 1,000 grams,....." and it still only meets the CE and CPSC standards. Not even the slightly more onerous Snell standards. So you have shown us you can make a cycle helmet that is heavy and meets the lowest cycle helmet standards. You haven't shown us anything about how you are going to get that weight down to be acceptable, the venting up to allow you to do more than go downhill in it and the protection up to the motorcycle standards you are calling for. Would you like to try again?
Please, no...
