Hi All,
I had a rather unpleasant incident this morning that resulted in me getting to know the tarmac very well. The chain popped off on my s/s (most likely my fault for not putting enough tension on it) as I was out of the saddle beginning to go around a short uphill corner, and the momentum from standing and pushing hard threw me over the front and onto the road. My wrists and shoulder absorbed the bulk of the impact but I also came down pretty hard on the side of my helmet. My head is fine now, but I'm not too sure about the helmet..
So, as the subject suggests, should I be replacing it? It's less than six months old and of a decent quality (Met brand). The only noticeable damage is a few scratches but it's got me concerned. Given it's protecting my only head, I'll likely err on the side of caution but wanted to check the norm here..
Any advice appreciated.
