Okay I admit it, I have been riding without a helmet. I've only really been in the neighborhood and on bike paths, so I wasn't really worried about it. This weekend I saw a friends facebook post from several months ago, where a car bumped him off the road and he wound up cracking his helmet.
So now I'm thinking I will need a helmet at some point. I'm looking at the price spread and I see $20-$180. I can see some big differences between 20 and 60-70 ish helmets, above that and it is getting fuzzier. Any non speed reasons to go over 80 ish for a helmet?
