Yea he's a hell of a rider. I think that was his saddle bags hitting the ground that was making that noise. In one turn towards the end there was a nice puff of something right betwen the bag and the ground. But man, what a rider.
Impressive I will agree, but to many times on his lefts to much of his body to even the bike was almost into the wrong lane, well at least on the oncomming centerline, also some times he was riding the shoulder line. Definately not the sort of bike for nice beds like that.
