Which is a great idea but unfortunately it is a either/or solution versus the Brompton carrier-block and furthermore the Klick-Fix is a bit low with this solution which limits the choice of possible bags drastically. I am using an adaptor for the Brompton block which carries a click fix, making it sit about 10 cm higher. Much better in my opinion: More choice of bags plus I can use Brompton bags as well (what I am doing 90% of the time).
