Stop looking for footstools to get your bikes on and off your roof rack. Thule's Criterium makes mounting bikes much easier. Its sculpted wheel tray and support arm keep your bike in position while you secure it to the rack, while the rack-level dial-activated clamp firmly and safely grips the bicycle by the down tube. Unloading is a breeze, too. A push-button release frees your ride in the blink of an eye. The Criterium's dual-action wheel strap fits all tire sizes. The Criterium fits on square and round crossbars (sold separately).
