Wheel parameters and size distribution of wheel diameters (D, µm; nw: number of wheels), with plots of the number of spokes (ns: rhombus), number of teeth (nt: circle), and the diameter of the hub (dh, µm: triangle) in relation to the wheel diameter. Linear regression of ns, nt and dh, µm on D, µm are shown, where ns = 6.65 + (0.03 x D, µm), r² = 0.22, p <0.0001; nt = 19.44 + (0.04 x D, µm), r² = 0.17, p <0.0001; dh, µm = 31.81 + (0.37 x D, µm), r² = 0.47, p <0.0001. (Wheel diameter size classes: 10 µm.)
