So, I bought an EVS RC EVO neck brace on closeout. I just couldn't pass it up for $90. I know how much these help in crashes is disputed, but I figure it can't hurt. Plus I would be really, really mad at myself if I broke my neck when it could have been prevented for $90. Anyway, after 150 miles of trail riding so far this spring I have found another reason to buy one that I haven't read before. When riding through trail whoops, or after making a mistake that throws me around on the bike, I hear my helmet hitting the back of the brace. After riding I have found that my neck and upper back is much less sore with wearing the brace than without. I think the brace is preventing my neck from getting stretched out too far while just riding down rough sections of trail and through whoops. If it helps when not crashing, it probably will help when I do crash. I don't notice I even have it on until I hear my helmet hitting it, and it makes me less sore when done riding. What's not to love?
