How often should you replace your helmet?

I seem to recall reading somewhere that you should replace your MTB helmet every 3 years because the UV light will weaken the structure over time.
This of course could well be marketing BS distributed to make us buy a replacement helmet every so often, but it does worry me slightly that the protection around my head is slowly decreasing over time.
Any thoughts?

So you reckon it is marketing BS then?
Luckily I have never broken mine and my head is already XL so I don't want it to grow any more thank you lol!
Just stick with what I have then.
No marketing about it, helmets start to degrade from the day they are made; and for the sake of 35 quid every 3 years i think it's worth it... seems cheap when you think about what it's protecting.
Off topic... where abouts are you inn West Lothian? I'm in linlithgow
do u know of any good places around here to ride?

If your Dad hit the tree face first, I'm not surprised that his helmet wasn't damaged - how's his nose?
If you didn't learn anything today, you weren't paying attention!
Also he may work with polymers but I very much doubt whether it is complete Bs, everything wears out. I reckon it is more health and safety covering their backs, after that incident with fox forks and the disc brake a while back, companies can't be too careful
I'd say if you are confident that the helmet is in an *as new* condition you are probably alright but I'll be changing mine within guidelines thank you! Not that I'll have to make a concious decision to do so of course - I keep crashing :roll:
How do you know it isnt already broken. What are you going to do if it fails next time you headbutt something hard. Would you ride a bike with cracks in the frame. :?
My helmet is kept in complete darkness except for when it is on my head. This makes the UV argument go out of the water because other riders may keep theirs on a window sill for example.
If it doesn't move and should, use the WD40.
If it shouldn't move and does, use the tape.

Anyway, as it happens I will be buying a a new helmet! The day after writing on here how awesome my helmet was I crashed and broke it :oops: My head is fine though so it's done it's job, can't say so much about my shoulder though

Mind you, I've only just stopped using a Tioga aero lid that I bought in 92.
After all, the idea is that the helmet takes the impact and breaks instead of your head!
Then he should know better. UV stabilisers are widely used throughout the plastics industry.
Who does he work for?

I am just saying that because I love my 98 Giro Exodus RL...
It fits like an old pair of Churchs shoes (on my feet).
To be honest my head is worth the £40 every 4 years to keep it intact! I would much rather this then a painful crack in my scull!

If the polymers degrade regardless of wear and tear then we would need to know the date on which the helmet was manufactured - god knows how long a helmet sits on a shelf before its bought.
If it degrades because of exposure to the elements, sweat, etc then this is going to be very variable depending on how often someone rides, how they store the helmet, the weather and places they ride in. In this context, presumably the 3 years has to be a very conservative estimate of the life of a helmet.
Mind you, after 3 years mine normally smells bad enough that anyone I ride with insists I bin it!
