It doesn’t inhibit the fold in anyway. I’ve just never seen them as particularly useful unless you have something that you’ll use it for.
It obviously inhibits the fold if you’ve got something strapped to it.
I was looking to add purpose to my C-Line and I thought that, with a rack, I could use it for when I need to carry more stuff and my T-Line when i simply wanted to ride somewhere.
Is it worth getting a rack for my C-Line? Do they impact performance/folding?
