I have a bikes at work trailer at home and at work and thought it was the cats meow until my LBS got a Surly trailer in the other day. These things out do anything I have seen. Fully intend on trying to find a way to adapt the Surly wheels to my at-works. That alone will be a quantum leap. I cannot justify a third trailer at this time, besides the dummy can and does regularly handle 50Kg of groceries/supplies. If I was trailerless and in the market I would go Surly, the hitch mechanism is fantastic, frame sturdy and lots of potential. Yes it is expensive but then so is gasoline.
