The 4ZA Stratos stem is strong, light and durable.
Flanders, the Flemish region of Belgium is infamous for serving up the harshest cycling conditions- where driving rain, cobbled non-category climbs, snow and ice are the norm for its 6,000 racing clubs.
This place, the pounding heart of a passionate cycling nation where the most revered Spring Classics unfold, is the cold steel anvil where flesh and bone are forged into the greatest racers of all time.
This is Belgium, home to Forza 4ZA.
And it is here where 4ZA products are engineered, hammered into raw form by the roads themselves, and refined in competition.
