"used in the TDF..."

Love it, not with those components, early Dura Ace levers, Ofmega pedals, Galli crankset, Modolo brakes... You could always email Andy, he has a bike biz...I have no record of Basso having a big enough european distribution to warrant the dollars required to sponsor a tour team...

Bought as a frameset, cobbled together with parts affordable, used than abused, probably some significant time on a period turbo trainer....
