Helmet - how often to change?
Just been around to my bro's and he has a new Boardman helmet. I have to say it fitted me perfectly and is much more comfortable than my current giro indicator. He is younger and probably faster than me so I didn't feel I could make off with it So it got me thinking... How often are you supposed to change them (helmets, not brothers) ? I'm not sure if I want to be encouraged into spending more money on kit... I usually don't need any encouragement!
