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.

Getting the Right Fit
At Wiggle we measure each of our bikes to build accurate size charts for our customers. Our qualified team of mechanics then individually check each order, against measurements supplied by you, to ensure the size chosen is correct. Another reason you can have complete confidence when buying a bike from Wiggle!
If you are on the change over between sizes both options will fit. Racers and experienced riders would usually select a smaller size as this offers quicker handing. A larger bike offers more stability and is more suited to new and intermediate riders.
