[0014] Furthermore, the hub body has a bearing hole, and the length of the bearing hole is 100-110 mm.

[0015] Furthermore, the length of the bearing hole is 105 mm.

[0016] Furthermore, a countersunk hole is annularly arranged on the flange at one side of the second hub portion, and the countersunk hole is concentrically arranged with the brake disc mounting threaded hole.

[0017] Furthermore, a weight-reducing groove is annularly arranged on the outer circle of the rim mounting portion, and the weight-reducing groove and the rim mounting threaded holes are arranged alternately.
