    Platform racks strain on wheels, hubs and axles

    Considering that on a platform rack (1up style or Thule T2) the bike is held in place only by the wheels, wouldn't every bump that make the bikes swing put some stress on the wheels, hubs and axles, by making the retention devices act as a giant lever? Or is this stress actually much less than the stress of simply riding the bike?

    There is no stress on the wheels from a platform rack. The bikes is just moving up and down with the rack. And there isn’t that much pressure on the wheels. Just enough to compress the tires.

    Riding puts way more stress on a wheel.

    Yeah not really worried about the up and down movements, more about the front to back movements. The wheels kinda stay in place while the frame tries to move. But it's probably not that bad I guess

    I know there are warnings about slowing down going over speedbumps, but I always assumed that this was more about damaging the hitch/rack than the bike. Unless you are doing something really crazy...

    Not true. As you accelerate or brake, the bike will move accordingly, as well as up & down. That said, I don't believe it's going to 'wear the bike out' or anything like that. They've all held up over millions of miles on thousands of racks with no problems.

    Non issue.

    Pretty sure I abuse my wheels/hubs/etc way more going 20mph down Rocky trails compared to the movement when on the rack.
    Nothing to worry about.
