About the Rock Forged FF77
The Rock Forged FF77 is built using a flow-forming manufacturing process, a technique that applies high-pressure rollers to a cast aluminum barrel under heat, stretching and aligning the grain structure of the metal. This results in a wheel that achieves a higher tensile strength and reduced weight compared to traditional low-pressure casting, offering a meaningful performance advantage without the cost of full forging.
This Rock Forged FF77 is available in 18x9, -12mm offset, 5x5,5x5.5 bolt pattern. Finished in Gloss Black with Machined Spoke Faces.
