also the Giro, Tour de France, Turkey, California and Poland were mentioned for 2018. At least one of the already convicted riders (Durasek, Bozic, Koren, Preidler, Denifl) participated in each of those races though, so it not necessarily means that others were involved.So as i understand it they (the Seppelt Boys and the Authorities) already know their names for quite some time, but no consequences so far for the involved riders. They also said that there is a swiss pro who doped (not specified IF he is a cyclist though) and Mark Schmidt doped riders at the Tour de Suisse und Tour de Romandie.
And yes, the authorities know the names, but as it happened longer than 5 years ago, there are no criminal consequences. So it's down to German NADA to punish them (as there's a 10 years windows for them) - and they are usually fairly slow and not exactly transparent at all.
