My new touring bike, the Marrakesh, while great, is absolutely incompatible with the old-school Y-hitch and rebuilding the rear hub to accommodate a longer axle so I can use the Burley Steel Hitch connector seems an unreasonable length to go. I read this thread with interest. I'm thinking I could bend some aluminum tubing into a seatpost-connector arm that I'd mount to the old trailer. It seems to me that the Travoy mount only allows for side-to-side play. How does the trailer/Travoy stay on the ground when the bike leans, as in a turn? Doesn't the hitch need to allow for more of a universal rotation? I'd appreciate the insight of anyone who has experimented with adapting to a seatpost mounting system, as done in the thread. How did you overcome the physics involved, here? How does the Travoy do it?
