Bicycle frames are constructed from materials which place emphasis on being strong, lightweight and stiff to aid power transfer. Aluminium, titanium, steel and carbon are widely used in all levels of frame production.
Major bike manufacturers produce a new range of bikes on an annual basis and this determines the model year of a particular bike. This annual turnover is fuelled by advancing technology, industry trends and customer demand for a particular feature or style of bicycle.
Wilier was born in 1906 thanks to the brilliant idea of a trader from Bassano, Pietro Dal Molin, of building bicycles on his own account. His forge or "Steel horses" rose as a small workshop along the banks of the river Brenta, at Bassano del Grappa, and it became more and more successful by keeping up with the increasing demand for bicycles.
