From the actual website
http://www.anirudharao.com/index.php?/project/kranium/When tested against the British Standards (EN 1078) at the Imperial College, Kranium absorbs 4 times the amount of impact energy when compared to regular cycling helmets.
It's stupid to drop one on the floor, very smart to buy a good quality helmet.
Actually, you're supposed to replace ANY helmet that's dropped. Since you don't know if it's compromised or not...and you'd potentially find out in a manner you don't want to I suppose.Not me, half the people in this website claim that if your helmet rolls off your kitchen table you have to buy another $600 helmet, even though the helmet or the visor are not cracked. I also want to know there they discard their expensive dropped helmets to collect a few.
Are you trying to make me believe that the guy in the pic received that face damage because when he crashed he was using a helmet that dropped off the seat of his bike? Please. And are you telling me that he would have not received that damage if he had been wearing an identical but never-dropped helmet? Yeah okay.
Show us your research numbers.
Facts please again.Not me, half the people in this website claim that if your helmet rolls off your kitchen table you have to buy another $600 helmet, even though the helmet or the visor are not cracked. I also want to know where they discard their expensive dropped helmets to collect a few.
I've NEVER dropped a helmet and I handle it like it's worth $1000. So buy your cheap helmet and throw it around but don't think that a cheap helmet is more durable than an expensive one.
The whole point of a helmet is to absorb the energy from an impact, lessening the chances of a head injury. The inner lining of a helmet is constructed from a special foam that'll crush in the event of an impact in order to increase the stopping distance your head has to travel before coming to a dead stop; in other words its "cushioning" your head in the event of impact. Once the foams been crushed, its done its job and will no longer offer this protection.K I crashed at ~130km/h in my Joe Rocket helmet.
I crashed again at ~40km/h stunting with that helmet.
Both times my head smashed the ground. Both times I felt nothing nor did I suffer any damage to the head.
I still wear it (occasionally). I trust it more than anything. GO JOE!
Don't care what anyone says I'm never letting it go.
Yes a dropped or even crashed in helmet is still a million times better than no helmet at all.I don't know much about how well dropped or not dropped motorcycle helmets protect you because I've never had a spill where my helmet took damage.
What I do know, first hand experience is with snowboard helmets. I wear a snowboard helmet two seasons before I replace it, I snowboard about 20 times a season and have 3 or 4 really bad wipe outs. These wipe outs are at around 60km/h, going as fast as I possibly can, somersault in the air, land on my head HARD on patches of ice and slide down the slope as I come back from blacking out.
What hurts the most is probably my butt or shoulder.. but my head? Never a scratch or headache or bruise. These snowboard helmets are about $100 and take a beating over and over and over again. They are made of foam on the inside, much like your bicycle helmet.
If an Arai $700 helmet has so much more tech than your typical Red snowboard helmet and they take A LOT of abuse, then I'm sure dropping an Arai off the kitchen table will weaken it but it will still protect you. I strongly believe the whole if it drops, replace it, is due to liability concerns. Everyone says that if you take one fall in a snowboard helmet, you should replace it but they keep on protecting my noggin' and that's first hand experience.
