It's funny this thread pops up on many outdoor forums I frequent (snowboarding, kayaking and biking)..and I can't believe people still debate the choice..
Sometimes I feel those who will not wear helmets are selfish
1. To their families who may end up visiting a vegetable in hospital for the rest of their lives
2. To the state who will have to pay for this persons freedom of choice
After having worked in maxillofacial surgery and seen my fair share of facial and head injuries, helmets will not always save you but boy you'd be a fool not to consider wearing one.
Here endeth the sermon
Here begenith mine. I predict very soon this thread will turn nasty. They always do. There is another thread running to about a thousand pages in the Off Topic forum that actually has some research from both sides of the debate.
I take it that as this post is in the Retro Tractor and Nasty Mud forum the OP means offroad? In that case as far as I'm concerned, yes. Unless it is a bimble along the canal towpath I'll wear one.
In fact I have just got a new one. I still don't like the thing but it is around fifteen and a half times better to wear than the old one.
On the road where I do most riding now? Apart from on the fixed, no, not very often. I'm not convinced it will do much, (see other thread) and, having read the instructions that came with my recent purchase I'm even less sure.
To be honest, if the law changed tomorrow, I would probably stop riding. Until the law changes it is my choice. You take risks every day. I go out in the sun (although never without Factor 15), I drive a lot of miles on the motorway, I eat my wife's cooking (occasionally). All these things and many more I consider more dangerous potentially than going for a ride on my bike.
If the OP is looking for a lid, you could do a lot worse than the Specialized S3. And that is from a disliker of the things.
Today's mood... Middling, middling to poor.
