I think those tufts are slowing him down.
I'd like to see what Lance could do on a bent, but he gets paid way to much money to stay on a DF.
As a bent rider, I think it's ridiculous that they go to great lengths to minimize drag on a DF frame, and even allow an aero helmet, but they won't allow recumbents, which in the hands (legs) of a rider like Lance, would fly. Speeds would jump incredibly.
