I have a Yakima Rim Roc 3 hitch mount bike rack for trade. It holds 3 bikes and has a cable lock as well as hitch lock. It fits a 2" hitch. The bike mount from the rims so it will accommodate any frame type without the need for a top tube add on. Here is a link to a review and pic in use.

Not looking for anything specific, just something of value and does not need to be cycling related. I am in Irvine.
