dropping lids

[The Pits]

is it really true that the thing is knackered after a fall to the ground? Mine fell off the fuel tank at a petrol station which is of course a classic dufus move. Trouble is, it was brand new, special edition, full monty, Rossi winter test excalibur AGV ti-tech number. Doh!

[randlemarcus]

Do AGV do a checking service? Wouldnt recommend that you use it in anger again until its been checked, and if necessary binned.

How are the ti-techs anyway. Was looking at that lid the other day in a "wondering if the 46 comes off then might buy one" sort of way

[makatya]

That is what they say.

P.S. Check the wording on your contents insurance for your collectors edition mantelpiece display objet d'art

[The Pits]

I rate the ti-tech. The range of sizes is good, the visors don't fog and they seem very well made. And the winter test paint job is stunning.

Or at least, it was.

Yup.

Expensive lesson learned the hard way, so it's a mistake your unlikely to make again.
As said above, you now have a nice collectors edition mantlepiece ornament.....

Yup.

Depends if the polystyrene on the inside of the shell was compressed - aslong as there wasn't any weight inside, it should be o.k... If the shell's not cracked aswell... worth getting it checked before buying another.

Arai do an X-Ray service - perhaps AGV do?

The bonnet came off my westfield and hit me square in the forehead and gave me a headache for 2 days. Through the hole where the air vent was I could see that the inner core was compressed so I slung it and got another. If it didn't land on the bottom edge I'd get it inspected or just replace it (although the odds of having a crash and hitting your head on the floor in the same place are pretty small the possible outcomes are sufficiently unpleasant).

[Phone_Monkey]

Would definitly replace it, you only have the one head. If you can get it checked out then it may work out as cheaper, if you can't why take the risk?

I had read somewhere that the way helmets work is that they compress from the inside - i.e. in a crash your head moves inside the helmet and compresses the polystyrene, rather than the shell flexing and pushing the polystyrene inwards.
Although dern's incident would appear to discount that...but is it also possible that when the bonnet hit the helmet, it was just like a normal impact, and so the head was the cause of the polystyrene compression?

If you can get it checked I'd do that, that will tell you if it's safe. I would think any bike shop could help you out there, at least pointing you in the right direction?

[Andy OH]

Question is, how much do you value your head?

I never leave the lid on the tank of the bike as it's too easy for it to fall off. If you do take your lid off the get fuel then stick it over the mirror or put it on the floor. I know it's a bit of a bummer especially as it a new lid but I would replace it and keep it as an ornament in the garage. Expensive lesson learned.

Of the two things that can cause the compression the pointier bit will probably compress the polystyrene the most. In my case the leading edge of the bonnet was substantially more pointy than my head but if I fell off my bike my head would probably be pointier than the floor it hit... if you see what I mean.

A bike magazine did a test of helmets to check the maker's claims that you should always replace them after a drop.... I think they ended up throwing one out of a 1st floor window and found it to be ok.

It does of course vary from drop to drop... I'd say that if your lid isnt cracked then it will probably be ok.

I love AGV helmets.

Get it checked for piece of mind, but I'm sure it will be fine.

I have a shark helmet that I wore on a huge trip and it got kicked about, bounced off the floor of a ferry, hit the ground when I fell off etc. It looked an utter mess, covered in scratches etc but I got it checked and it was fine.

I wouldnt have though a petrol tank drop would have done that much damage!

Had a mate who bought a 2nd hand Arai(money,latest thing etc) had a spill, not here now,might not of been the lids fault, but we'll never know! you can usually get it replaced on your house ins, i had 3 new ones courtesy of the ins man.(very accident prone)

Yeah I think I know what you mean, I guess at this point I'm unsure whether helmets are designed to compress from the outside (initially I had thought that, but then I read about it a bit and it seemed that the outer shell should stay solid and your head does the compression inside the helmet). Sounds like the best thing that can be done here is to get it checked and remove all doubt

That was an MCN test. It left me a bit confused....until I remembered that MCN write complete boocks most of the time and I returned to the previous view that helps that have falled more than a couple of foot onto something hard should be replaced (or at least checked)

[NorthernBoy]

I'd tend to agree with those who say it could well be fine. The inside did not get compressed, as there was no head in it at the time to compress it. The only thing to look out for is damage to the shell. Lok at that very, very carefully, and, ir it is not cracked, or bent out of shape, just go on using it.

A drop of less than three feet, empty, should not do any serious damage.
