    ATOC top carrier shaking....scary!

    I have a ATOC carrier in top of my Subaru Outback that I use to carry my tandem. The carrier is attached to the factory crossbars. In certain wind conditions, like when getting near semis the bike shimmys. I feel that there is plenty of strength in the setup but still can't relax and can't keep from looking through the moonroof to check on what's happening which isn't very safe either. Also this is the type of rack where you remove the front wheel.

    Has anyone else experienced this? Is there a fix or should I just close the moonroof and not worry about it? ( hard to do)

    The ATOC is a pretty solid piece of kit so I would look at the stock mounts and crossbars. When we bought our ATOC both Yakima and Thule recommended changing to their racks. I wiggled the factory rack on our Ford Escape and felt is was solid enough, but it does move around more than the Yakima or Thule racks. The dealer had both brands mounted on employee's cars and I shook them all. Also most factory racks have a slight curve that matches the roofline of the vehicle. This means that the bike leans out a little bit when mounted rather than riding straight up. Front wheel removal racks are best for aluminum or carbon tandems. Our Cannondale tandem owners manual specifically mentions to not clasp the tubes when mounting it on the car.

    Maybe you can get a passenger to carefully watch the bike while driving to see what is going on.

    I think you can buy a diagonal brace. You might give ATOC a call. I use the factor rails on my Jetta wagon, but Thule cross bars, and have never had a problem.

    I have to ask, are you sure it's the bike, or might it be that it's the car that's doing the movement? I have the RockyMounts rack, and while the tandem will shake some, the majority of the movement I feel is the car & tandem being shaken by the turbulence coming off the bigrig.

    I agree you might want to use Thule or Yakima crossbars. We have a Yakima Sidewinder on Yakima crossbars on the factory rails on our minivan, and I can shake the whole car by grabbing the Sidewinder.

    Sounds like aftermarket crossbars might be the answer. Next question, how do I incorporate new crossbars onto my factory Subaru rack? I've looked at both Yakima and Thule's web sites ant this is far from clear. Will I have to drill holes? Sorry to be thick headed!

    I'd talk to Yakima, or Thule about your specific make, model and year
    .
    You could fall off a cliff and die.
    You could get lost and die.
    You could hit a tree and die.
    OR YOU COULD STAY HOME AND FALL OFF THE COUCH AND DIE.

    You need something like this.

    I used this setup with my Rav4 and ATOC until I got a truck and shell.

    +1. I've been using those mounts on my Jetta wagon for almost four years without a problem

    We used an atoc on a VW Eurovan, the roof pops up, so it allows movement in the racks which multiplies to the bike, I think Rick's idea of a brace is the best.
