Oh, so do the more expensive helmets protect you better than a cheap one?
Some do, some don’t. Do your own research, make your own choice. I don’t spend the money unless I can see real benefits and in some cases there are. Been skiing, biking for a long time and head protection has always been a priority for me so I make the effort to research and then buy what I believe is the best option. Unfortunately, I have never found a budget helmet that meets ALL my requirements i.e. safety, quality, fit, detailing etc, etc.
Your Carrera Edge does look very good for the price, but it doesn’t have MIPS for a start, which I think is worth having, and it’s not exactly cutting edge light either. If money was no object, there are better helmets out there, hence my comment about buying the best you can afford. That doesn’t mean chucking money at it for the sake of it as you wrongly presume.
