In the bicycle aftermarket sector, upgrading suspension components is a common requirement for improving ride dynamics. A client commissioned us to manufacture a custom CNC machined aluminum swingarm designed for a mid-mounted suspension setup. The primary engineering objective was to significantly reduce the weight of the component compared to the stock part, without compromising its torsional rigidity and load-bearing capacity.

To achieve the desired strength-to-weight ratio, we utilized high-grade aluminum alloy processed via multi-axis CNC milling. The design features extensive strategic hollowing, which removes excess material while retaining a robust skeletal frame. Critical mounting points, including the pivot holes and shock mount interfaces, were machined to strict tolerances to ensure accurate alignment and eliminate play within the suspension linkage. Finally, the CNC bike component was treated with a black anodized finish, providing excellent corrosion resistance and enhanced surface hardness for demanding outdoor environments.
