I saw this over on Urban Velo.
I have a Cetma 5 rail rack on my rain bike- and love it for hauling stuff rain or shine. This is a cleaner looking mounting system, that is supposed to be super strong as well. It retails for $120 powdercoated, or $100 if you want bare metal. I like the little knob things that you can mount lights onto as well. More info and pictures at the Cetma Cargo site.
