What a load of BS.
first: yes, they were more than likely on epo. And yes, OPQS likely isn't clean either.
But, as someone else already pointed out: gewiss in 1994 (2 years earlier) was as ridiculous (fleche wallone, giro, tirreno adriatico, countless other races), or even more.
After this year the 50% hematocrit limit was set and suddenly Riis wasn't the best climber anymore and nobody was able to blow things apart on the Poggio or Cipressa in MSR. But that also meant that the few teams who didn't jump the epotrain finally knewwhat was happening and what to do.
That year Mapei was trounced by gewiss in MSR and AGR (Colombo and Zanini), MG in RVV and LBL (Bartoli and Richard), in the giro by Tonkov and Zaina, by telekom in the tour (Rominger -who won 4 GT the 4 years before- barely got in to the top10 of the tour),...
By 1996 rampant epo use was widespread in the peloton, with the exception of some Belgian and Dutch teams (Lotto finishing the tour with 2 riders, Edwig Van Hooydonk quitting cycling at 30, disgusted by all the riders the flew past him and he easily beat 2 years before,...)
