Sosenka, a rider for the Acqua&Sapone team, was riding a Moser made from aluminium tubes.
Should Lance Armstrong ever take a crack at the Hour record - he was reported to be thinking about it last year - he would ride a carbon Trek.
Chris Boardman is currently commentating on the Tour de France for ITV2 in the UK. No doubt, he'll mention Sosenka's feat on tonight's programme.
Antonello Della Corte, general manager of Vuelta wheels, said:
"Sosenka has accomplished his record riding a Moser bicycle and Vuelta Italy wheels: technology entirely made in Italy."
