Vortex Racing 520Z3D-120G VTX Chains

The EK Z3D Series Chain sets a new standard in chain design, combining aesthetic appeal with outstanding performance characteristics. Each outer plate features a striking 3D curved shape for enhanced stiffness and maximum power delivery to the rear wheel. The dimpled outer plate adds extra strength, while cutouts in the inner plate reduce overall weight and maintenance requirements. These features, combined with chromium carbide roller pins, ensure smoother engagement and reduced friction compared to traditional chain designs.
