Yes, concrete roads are rough with expansion joints and dips. Plus they are hard on tires. That stretch of road floods everytime we get a good rain and has deteriorated the road conditions. A friend of mine has a top of the line Gopro. Today at lunch I mounted it on my helmet and went down the same road that my video was taken. That video was actually more shakey than with my camera. Guess my head actually bounces more than the bike does. Now his lower speed on smooth road video was fantastic, but I could buy 10 of mine for his one. For what I want mine is going to work fine.Concrete roads are a Pain in the neck aren't they.
