No surprise, if he did break the rules I’d imagine everyone knew it. They knew it because they were cheating too.
USADA [note: not UCI] has said the Tour titles should not be given to other riders who finished on the podium.
The agency said 20 of the 21 riders on the podium in the Tour from 1999 through 2005 have been "directly tied to likely doping through admissions, sanctions, public investigations" or other means. It added that of the 45 riders on the podium between 1996 and 2010, 36 were by cyclists "similarly tainted by doping."
