What a Cracked Bike Crash Helmet Looks Like
The crash that gave me my concussion in March 2018 hardly seemed to have affected the brand-snew helmet. But exerting force would open up a crack in this area as shown below.
In my December 30 2018 bike crash, a very obvious crack is seen. The sunglasses were also damaged, which presumably means my eyes and nose area got a little protection—I always wear protective glasses, night or day.
Giro has discontinued the Giro Aero model I like, but I was able to scavenge a new one on closeout. The new models are too heavy for my taste—it matters with the head extended out for 200 miles, plus the new system cuts into my scalp in back when I tilt my head up.

The apparent impact site.

Most of the helmet looks OK; the impact was in front.

It’s hard to say what would have happened to my eyes without sunglasses: something could have wedged into an eye socket, for example.
