I missed that fietsbob said the two wheel trailer, so I apologize. He was being helpful. I use to have a BOB trailer that I used with my old fixed gear, but I sold it because it seemed a bit too unwielding. However, this problem wouldn't be as bad with a two wheel trailer.

Now how would a p-clip work on the bottom of the rack. That seems like the best option for me, but I am not sure how that would work. Yes, I have a front brake.
