I've got a Saris 2 Bike Rack for Sale. It's an upright mount that locks down over the front wheel, so the rack doesn't touch the frame. It fits a 2" receiver. Also, there is a slight bend at the base where it flips up, so it will not flip up, but it hauls 2 bikes just fine. It was $400 + new, but I'm asking $80. If you are interested or have any questions, please let me know.
Thanks,
Rusty
