So I did my first solo crash of the year today. I was drafting and zoning out (lesson learned!) and my wheel overlapped. I didn't realize what was happening until I got slapped down. I landed in gravel on my right shoulder, slid a bit, then my head came down on my right side and I rolled completely over. I was only going 12-13mph at the time of the accident. So, in your opinion would you replace your helmet or should I be okay riding in it?
