Did 27 miles trying out a Cobb saddle with strong headwinds. Uneventful until I decided to go down by the water to take a break and look at some boats. Up on the sidewalk looking out I missed seeing a cutout for a drain in the sidewalk with about a 10 inch drop. Before I knew it I was down and picking myself up knowing I banged my right cheek and a few finger cuts. Rode the last 12 miles home and saw a scuff mark on the front of my Giro helmet and then saw the rather large crack all the way through. Apparently I hit my helmet first and then my cheek. Helmet is toast but saved me a skull fracture. Well i was looking at the new Giro Aeon and just ordered but not exactly the reason why I wanted it.
