There are a number of counterfeit Confentes because they're big-dollar bikes. There are also lots of faked "Colnagos" because of the power of the brand name and availability of decals - in some cases not to defraud buyers but simply to make the owner feel better about his ride. Happens with Schwinn Paramounts, too, for the same reasons. Another high-end bike that has had its counterfeiters is Hetchins - usually the crudity or inaccuracy of the lug shapes gives them away, though a few are very nicely done.
