Ha ha!giantsaam said:It just depends on which end you want to run into your garage with.
Seriously? Any difference in drag is going to be so insignificant that you and your fuel economy will never be able to detect it. If you are concerned about fuel economy, look into mounting the bikes behind the car, not on the roof.pbbullpup said:I'm wondering which way would create less drag too.
I run two way on the outside of my WRX wagon (outside of the 'feet') when my ski rack isn't on, they are far enough to the side that the liftgate can clear them.honkinunit said:If you have a choice, run it facing forward. Here is why.
I had a 2002 WRX wagon, and because of clearance with the tailgate, I had to run the rack backward. One day I went for a ride on my road bike, and when I got done I was a little wasted and spacey, and I clamped the fork in, but forgot to strap the rear wheel into the tray. I got on the highway, and when I hit about 65mph, the wind lifted the rear wheel out of the tray, and the bike pivoted back around the front axle clamp so hard that it came out of the rack altogether. Imagine my surprise when I heard a big bang, and looked in my rearview to see my $3000 road bike flipping down US36. Ouch.
The bike ended up right in between lanes. Traffic somehow avoided it for the 2-3 minutes it took for there to be a gap big enough for me to retrieve it. I just tossed it in the back of the car, thinking it was toast. Believe it or not, after replacing the rear wheel, one pedal, and one crankarm, I am still riding the bike....Ti is tough stuff!
Bottom line, if you make the mistake I did, and you are facing forward, the bike might pop out of the tray and dance on your roof a bit, but it will probably stay upright and safe. Put it backward, and you may get a different story. Of course, you hope you always remember to strap the wheel in, but given the number of people who tear bikes off their roofs driving into garages, you are better off minimizing the possibilities.
YMMV.

I agree look out for running it backwards due to physics but there is always a hidden meaning.Like earring in the right ear kind of meaning if one chooses the posterior mounting method, you might find unwanted company following you to the trailhead. That is of course unless you like that kind of thing.:thumbsup:
Not so. My car went from ~22mpg to close to 24mpg on the Moab outings with the bikes facing backwards vs forwards on the Sportworks Bob Rachet rack (T2 prececessor). The added benefit of not having insects cake up the stanchions was an added bonus.Nickle said:Seriously?

There are a lot of factors that contribute to fuel economy and I doubt any were equal during each of your Moab trips where you observed 22 and 24 mpg. To say that bike orientation is what caused the difference is inaccurate.MK_ said:Not so.

Sure, that's the best singe serving measurement to present, though. I also observed an increase in average fuel economy (the computer holds an average over 1000 miles or so; on top of that when I lived in Boulder and worked in Boulder the only time I touched my car was to drive to the trailhead). The trips above were numerous in each configuration. In each case there were 2 bikes involved.Nickle said:There are a lot of factors that contribute to fuel economy and I doubt any were equal during each of your Moab trips where you observed 22 and 24 mpg.

I bet the bikes get helluva motion sickness on your T2. I almost got motion sickness just looking at them, driving behind you.icegeek said:Besides, the bike are less likely to get motion sickness. They're delicate, you know.
