APEX's new forgings weigh as much as 120 pounds before machining. To form such a thick blank APEX requires special equipment capable of 10,000 metric tons of pressure. This extreme pressure increases the strength of the aluminum by eliminating porosity and improving the grain structure.

Many companies use 3rd-party blanks intended for non-motorsport wheels which can severely limit sizes, concavity, spoke design, and critical brake clearance. APEX designed their very own blank profiles from scratch to give us total control over the final product.

One of the most noticeable features of the SM-10RS is its use of side-milling on both sides of each spoke, creating an I-beam effect. Any excess material that doesn’t add strength is carved out using a precision CNC ball cutter. Side-milling is often deemed cost-prohibitive by others, but for true performance without compromise, we believe it's essential.

The SM-10RS is not just another style to choose from. APEX used Finite Element Analysis of bending loads to optimize spoke geometry for greater stiffness without increasing weight. In fact, the SM-10RS is nearly identical in weight to the popular VS-5RS yet almost 10% stiffer, and 25% stiffer than the first generation of forged wheels.
