Wilier Triestina was started in a modest workshop on the banks of the river Brenta in San Fortunato by Pietro Dal Molin from Bassano del Grappa, Italy in the summer of 1906.
The company name originated as an acronym for the phrase “W l’Italia liberata e redenta”, where the W is an abbreviation for "Viva!" (Long live Italy, liberated and redeemed) Triestina comes from the name of the city of Trieste. When Wilier was founded, Trieste was not part of Italy; the name 'Wilier Triestina' reflected a patriotic desire for it to be rejoined.
The famous Italian cyclist Fiorenzo Magni rode Wilier bikes in his 1948 Giro d'Italia win as well as his 1949 and 1950 Tour of Flanders wins. More recently, Marco Pantani rode the 1997 Tour de France on a Wilier.
