Several months ago after buying a new car, I puchased a Saris Bones trunk mounted bike rack. I chose this as: 1) it's less expensive than a roof rack system, 2) it's easily removed, and 3) it's supposed to be one of the better trunk mount designs. It has served me well enough for my normal, weekend trips to local mountain bike trails but I have to admit that I'm always nervous watching my bike bouncing around on what seems to be a fairly precarious perch. I recently happend to see a DC cop dragging his bike off the back of his cruiser as his rack came loose and fell off. I used to just throw my bikes in the back of my pickup and never had to worry. Now I'm always watching my rearview mirror with a knot in my stomach worrying about my nice, new Surly or Cove getting bounced right off the back of my trunk as I hit a bump or round a turn. I'm getting ready to leave for North Carolina for a MS 150 (a 7 1/2 hr trip from DC) and have to admit I'm a little nervous of that much highway driving with my bike mounted on this rack. Of course I tighten the straps and check their tension frequently, but I did have a strap come loose on only a 5 or 6 mile drive recently. Given that I can't afford a roof mount system right now, does anyone have any recommendations for securing a bike or two on this type of rack where I won't have to worry?
Thanks as always.
