Vitus was a bit revolutionary in Europe in its day. The frame is made up of aluminum tubes glued to aluminum lugs. It makes for a real pretty aesthetic. This one is all original, aside from the rubber and bartape. It's seen new grease and balls in all bearings, cables were in good shape. I believe this is a 54 cm bike. This baby broke apart on its maiden voyage after it was sold. Rather dissapointing. Let that be a warning to us all- don't ride glued bikes!
