I have to upgrade my bike carrying capabilities on my car. I have been looking at Yakimas roof rack systems rather than a hitch rack because of the versatility of the roof rack allowing me to carry other things like canoes, gear, or anything else I can strap up there along with my bikes. I also like the fact that the bikes are upright with the front wheel left on(King Cobra) and no touching of painted surfaces. In a rear ender fender bender at low speed you also have a chance for your bikes to survive. Security I believe is also a little better due to the increased visibility of the bikes. Whats the cons of a roof mounted rack system? Is the Yakima roof rack a good roof rack? Thanks!
