The Thule Big Mouth is a solid upright bike carrier for your roof rack cross bars. It features a self-adjusting frame clamp and wide wheel tray.

This convenient 1 bike system mounts on Thule square bars, as well as other square or round bar racks. Add a Thule lock cylinder to lock both your bike and the Big Mouth to your roof rack (sold separately).Does not fit OEM factory roof racks.
