Well, I don't know a phylangie (sp?) from a carbuncle, but if that (the apparent hump), were Lance's problem seems like we would have seen it (and heard it widely commented on) before now, don't you think? My purely-uneducated guess would be that it's something they're working on for aerodynamics. One of Graham's pictures seems to indicate something similar on George Hincape. My 8.5 cents worth.
