No helmet. Most of my mates the same.

Helmets are used for aero advantage in time trial racing here in the UK. We are not required to wear helmets in our races unless you are under 18.

I wear a homemade head foil that fits tight. There is no padding. This kind of head gear is worth 3-7 watts over the best real helmet aero shape.

We have a *Classic* class for non-aero bikes and no helmets. I race both divisions.

IanH,
Do I understand your homemade aero helmet is 3-7 watts faster than a store bought aero helmet? What is the biggest difference that causes the 5watt improvement?

Can you estimate what difference an aero helmet makes over a regular store bought helmet and/or no helmet?

The head foil is narrower because it does not have to accommodate padding. Mine is one layer of glass fitted flush to my head. Like a bathing cap. Very easy to make in your kitchen.

One of our better riders is an RAF pilot and a clever lad. He has built a homemade wind tunnel with wired sensors attached to a sliding platform. On the platform you place the foil or helmet. Its movement backwards (resistance) can be measured to a frightening degree. He has a chart that relates to watts. He is a brilliant fellow. And quite quick.

Forgot the second part of your question. Bare head, helmet, aero helmet.

A bare head with very short hair tested better than any standard bike helmet. I do not have the watt differential but remember it was significant. Only the special aero helmet is an improvement over the bare human head as per the tests.

This made me laugh.

I know of one lady who has included an Ipod in her aero helmet. Everything tucked in the boot.

I'm working on a tele to reflect off my glasses en route. Then I can follow the lads of Manchester United.

Only dubbing.

My childhood friend got brain damage when he flipped the bike. Never was the same after that. I ran into a post at age 45 but had a helmet that carcked, but my head stayed together with just a small concussion. Helmets are cheap compared to brain damage. Check out these good deals on helmets. . I see people all the time without them-- do we have to learn this lesson all over again?

around here we have a name for the idiots who don't wear helmets- organ donors. Been through three accidents with head hits and three new helmets after three concussions and positive brain damage if I had not been wearing a helmet.

There are far more fatalities (and head injuries) when driving a car compared to those on a bicycle, yet drivers do not wear helmets? This nonsense about "we call them organ donors" or "do we have to learn this lesson again" is really the pot calling the kettle black considering how little factual evidence there is to suggest that helmets actually save lives.

Below 20 kph (~12 mph) you are more likely to fall and hit the ground or obstruction with your hands/arms/shoulders/knees and hopefully walk away with some scratches or bruising at best, or a broken bone at worst. Above that speed, an impact is serious enough to kill, regardless if you are wearing a helmet or not. This is based on various reports on hospital visits by cycle accident victims around the world.

What about those who suffer neck injuries or even death as a result of wearing a cycle helmet - the helmet causing the damage when it fails (as in the concussion examples posted above) or, for example, the helmet getting wedged under a vehicle in such a way that the cyclist cannot escape?

bikenewengland: your post is little more than anecdotal evidence - there are hundreds of such 'experiences' reported, yet they are still minor compared to the overall number and types of accidents or deaths related to cyclists - and doubles as a veiled advertisement about products that are substandard at best and actually fail when put to the test: "...helmet that cracked, but my head stayed together with just a small concussion". Had the helmet been up to even the minimum of standards for a motorcycle helmet (which is DOT certified), you would not have destroyed the helmet and possibly have been spared the concussion. A product that fails is not a good product.

hippiebikerchick: insulting people you do not know based on an opinion with no supporting facts is "forum troll" behavior at best. You've been in three accidents where you had to replace the helmet three times. There seems to be a pattern forming.

Recent studies are beginning to show that car drivers actually drive closer to cyclists wearing helmets. There appears to be a false sense of security being developed on both sides: the driver thinks the cyclist is safer and is paying attention; the cyclist believes the helmet makes them safer and typically begins to take more risks.

Educated cyclists are the ones that know the limits of their bodies and the equipment they use. Proper knowledge of road conditions, driving defensively, using mirrors/bells/horns/lighting and being aware of your surroundings (other vehicles, pedestrians, cyclists, pets) will save your butt far better than any current cycle helmet in existence.

That said, people should not be required to wear helmets. In the end it should always be a choice to wear a helmet once you are fully educated as to it's limits or benefits. Insulting people into a guilty feeling based on sketchy information or anecdotal stories is just bad form, and a pitiful attempt to lobby the use of helmets.

I do support wearing helmets in increasing your safety with certain uses: it's a great platform for mounting additional lighting (fore and aft), or for adding a visor mirror to increase your awareness of traffic. Occasionally I wear one when I know the roads I will travel are alongside highways where the chance is good of getting hit in the head by stones thrown by cars/trucks. It can also be good for keeping the head cool or warm.

But please don't assume it will save your life, or make you safer! Only *you* can do that.
