I will say to a first approximation, 100% of the RadioShack lycra liveried carbon fibre Trek riders I see riding through Sydney traffic on a weekday morning are _not_ Lance Armstrong class riders.
(Not any more than I'm a Carl Fogarty or Troy Bayliss class motorcycle racer when I put my racing leathers on and fire up my Ducati Monster...).
It's mostly posing and toys, with an unhealthy dose of brand snobbery and wealth signalling (and being brutally honest, I'm guilty of a little bit of both of those myself - no matter how much I protest that "My Ducati is just a fun toy! I;m not a brand conscious poser! Not like those _other_ Ducati riders...")
