Cannondale OPI Steerer

Cannondale’s patented OPI 3D forging process allows them to take parts that normally consist of multiple pieces of bolted, bonded, or welded aluminum, and instead, use a single block of aluminum to create one-piece forged parts. By forging the pieces from a single block of aluminum, Cannondale achieves exceptionally good metal-grain alignment. This makes the parts stronger and uses less material for overall lighter weight.
