I am selling a lightweight titanium rear carrier (black) for Brompton bikes. It's lightweight, weighing only 175 grams. I only used it for about a month after installing it. However, as you can see in the photos, there are some scratches. Despite this, it's well-made and has seen little use. I'm selling it because it didn't fit the click-fix adapter I have. As shown in the photos, the item includes only the carrier itself. How about using it to lighten your Brompton?
