I really enjoy my BOB trailer, but the more I check my folder on flights, I consider getting a sturdy travel case instead using cardboard box and duct tape. I like the idea that the BF case can morph into a travel trailor. However, from looking at pics, it looks like it wouldn't roll quite as smoothly as BOB. I also read someone's review stating that their BF trailer was very noisy throughout their bike tour. Does anybody here have one? Can you mount high pressure tires on them?
