not sure if anyone is interested in the Kinetic trainer, but I just got off the phone with them because I had the same concern about attaching my fixed gear to a trainer.
The nice man said their trainer will work with a fixed gear or BMX bike but that it requires smaller cones that they will send to you free of charge (shipping doesn’t count). Call the 800 number and ask about the BMX/Track cones and they’ll take care of the rest.
He went on to say that they prefer you buy the trainer retail rather than mail order. But if you insist on mail order call them and they will match any offer within the United States. Make sure you say “price matching” offer when you order. They’ll put the smaller cones in the box before they ship.
