Featherweight bicycle rear carrier

To reduce weight, I have built a featherweight bicycle rear carrier. The weight, without the 4 frame mounting bolts, is just 140g. The usable area is 370mm x 130mm. Although, not designed for heavy luggage, the luggage carrier withstands a static load of at least 70 kg (myself). To achieve the low weight, expensive handmade aerospace materials were used.

To give an impression of the weight, the luggage carrier is as heavy as this ebike computer:

My bicycle was equipped with the Tubes Airy rear rack, but I couldn't use it because of the small size, which is 215mm x 66mm. With a weight of 350g, the Tubes Airy is the lightest commercial rear carrier.
