I bolted two 2" square tubes across the I-Beams and bolted a 4' receiver tube to them. The problem is that the TT does not have much of a suspension to speak of so the bikes bounce really hard. I have cosmetically ruined 4 bikes over a short period of time. Right now, I use pipe insulation (secured with a small piece of duct tape to prevent them from falling off) on the bike frame areas that appear to potentially rub. I also found a bolt on part from Cabelas that enables me to strap the bikes to a lower bar. This had significantly helped prevent the bikes from banging against each other.
I have a concept on the design board right now. I expect to have a working model by November and have it in production by Mar. '04. I will be working on legalities and marketing while the design is run through testing. I should have several units ready for testing by Jan. '04 that I would like to get out into the real world for feedback. If you are interested in a bike carrier that provides shock absorption, PM me and I will keep you posted.
