My Giro helmet is about 5 years old and seems to be still in fine shape.
A cycling friend of mine mentioned that there was a report about helmet age and that after several years, the styrofoam develops small invisible fissures from exposure to the elements, sweat and all that.
He suggested I get a new one. Can anyone point me to that study, and are old helmets bad helmets?
:confused:
My gut instinct is that yes, we should replace our helmets frequently. Because of degradation of the polystyrene due to ultra-violet light and ozone (exceeded my limit on $2.00 words today).At work our hard hats are supposed to be replaced annually for these reasons (doesn't happen). Personally, I go about 3-4 years for my helmets and hard hats. (I am cheap).
A more cynical person would say manufacturers push this for constant sales.

The plural of "anecdote" is not "data".
I read in last months bicycling magazine that most manufacturers recommend replacing your helmet every 7 years. But that it's a generalization. It depends also on how roughly you handle your helmet and how much it's exposed to heat and sunlight.
If everything seems under control, you're just not going fast enough...

I look at it this way- even an expensive helmet is less than the cost of my insurance co-pay and deductible for an emergency room visit for a head injury.
Nothing is so good that somebody, somewhere, will not hate it.
Pohl's Law
I'm going to replace my helmet immediately after this year's magpie season. That will be three years and I think that's quite enough.

This got me thinking, i have owned a total of 5 helmets in the last 8 years, i have never had the used same helmet for more then two years, however i have also never replaced a helmet due to age

Hey, I was doing a little research (damn slow day at work and wish I were outside riding instead of in front of this monitor) and came upon the Bicycle Helmet Safety Institute. Here's what they have to say:
So, looks like since I have yet to crash in my helmet after several thousand miles (unlike Joe) I may stick with my helmet for a while longer. Even though it isn't the most sylish, I can keep a few $$ in my pocketbook.Somebody is spreading rumors that sweat and Ultraviolet exposure will cause your helmet to degrade. Sweat will not do that. The standards do not permit you to make a helmet that degrades from sweat, and the EPS, EPP or EPU foam is remarkably unaffected by salt water. Your helmet will get a terminal case of grunge before it dies of sweat. UV can affect the strength of the shell material, though. Manufacturers put UV inhibitors in the plastic for their shells that control UV degradation. If your helmet is fading, maybe the UV inhibitors are failing, so you might consider replacing it. Chances are it has seen an awful lot of sun to have that happen. Otherwise, try another brand next time and let us know what brand faded on you.
No wait, I want a CamelBak, and new Time pedals, and etc. etc. etc.

Chris, you will always be the wildman of this forumI just dont know my limits. i dont crash alot... just one big crash every other year, not sure why, but thats been the trend for the last ~8 years.
The funny thing is, in all my crashes so far, I have never hurt my head (except for the day when I chipped three front teeth, fat lot of good my helmet did that day!), but I still don't have the guts/bravery/stupidity (strike out whichever doesn't apply) to ride without one. I'm afraid of Murphy's law striking!

If you crash and have ANY sign of contact on the helmet, ( scratches, dents, scuff marks etc.) REPLACE it- if the polystyrene is compacted at all, even a little bit, it has lost it's shock absorbing capacity and that's what saves your life.

If it ain't broke, mess with it anyway!
I have to agree with HillaryRose about the cost of a new helmet vs. a trip to the ER.Even though it isn't the most sylish, I can keep a few $$ in my pocketbook.
Both Nashbar and Performance have helmets on sale right now. I bought a second Giro helmet for commuting for under $20. Who cares if it's last year's model. I wasn't looking for the Pneumo anyway.

Though, have you tried on the Pneumo? That was a big mistake. What comfort, and I looked in the mirror and thought I looked just like Lance.Who cares if it's last year's model. I wasn't looking for the Pneumo anyway
Probably going to go look at a Louis Garneau. Best Consumer Report ratings.
If your helmet has been in use for 3-4 years, it has been exposed to ultra violet and infra red light, exhaust fumes, and sweat. These along with usual wear and tear, can effect the reliability and dependability of a helmet
Listen caefully:
The people telling you to replace your helmet are 1) the LBS and 2) the helmet manufacturers.
How do both of them make money??
This has been going around for a number of years, and is one of those urban legends with no basis in fact. Yes, if your helmet has been crashed, replace it. If it is falling apart, replace it. Otherwise, it should be fine.
.
Even the helmet manufacturers don't believe their own BS about helmet decay any more. They've switched tactics now and went with the fashion angle. Every year, there's a "new" model with more holes and freakier design for those who need to be seen in the latest gear. Seems to work - some of my riding friends show up with a new lid every year or so.
BTW, how do you get infrared light into this helmet thing? Very few people store their helmets under KFC chicken thighs warming lamps, ha ha ha. And what about cosmic rays? Aren't we bombarded by those all the time?
And a what a good thing THAT is!Originally posted by jaques

Jacques...do you know who those very few people are? I recommend that you avoid them, even if they are very wealthy...they ain't right!!
