Thanks illiad50, that is exactly what I am looking for. My mountain bike is a 29'er so I might not be able to go back that far, but it sounds like it is better than moving it in front of the sunroof. We use the sunroof a lot so I may go w/o the fairing. I'll try moving the front crossbar w/ and w/o moving the rear cross bar as well. Will let you know.
I'm also disappointed with the whistle if the rubber strip is not in place. I don't want to keep cutting it up as I swap out bike trays and other accessories.
Obscured1975 - that is the setup I have and it sounds like the setup illiad50 has too.
Thanks again.

 

Yes, I have the same setup. It looks nice and will work for my 19' kayak, etc.

Even with the fairing and the bars back 4", it still has a little whistle between 40 and 50 mph--and a bit more noise than I like at 70 mph, but no whistle.

I'll probably take it off for long highway trips when I have no toys on the roof.

I did not have to cut up the rubber strip to use the fairing--I just pushed the strip down tight around the fairing clips. It looks nice, but it might be the source of my whistle.

Let me know how noisy it is w/o the fairing--I may pull mine off if noise is the same.

 

Have a look at the latest in roof rack technology for your Avant.

I think this is exactly what you are looking for.
