Variable Cross-section Spoke Design
The spokes feature a gradual cross-section that is wider at the root and narrower at the tip. The thickest section at the connection to the central hub flange withstands maximum torsional and bending loads, while the tapering towards the rim significantly cuts excess material in non-critical load-bearing areas. Additionally, curved grooves are machined into the spoke sides to further reduce weight while enhancing fatigue resistance.
Deep-dish Lightweight Rim
The rim adopts a drop-center design with stepped weight reduction treatment on the inner side. The rim edge retains sufficient thickness to ensure air tightness and impact resistance, while the inner non-load-bearing area is substantially thinned, achieving lightweight performance without compromising strength.
