Carrying your favourite bike on the roof of a car makes everyone nervous, that's why we are proud to say the Swagman RACE READY Roof Mount Bike Rack was tested by the Canadian National Cycling team, passing with flying colours. Capable of handling all types of bikes, even up to fat bikes with 5" width tires, this rack is up to the task. The locking handle helps make sure your bike stays safe on the roof getting from point A to point B. The pivot arm can be switched from passenger to driver side with a few easy steps. Fitting a good majority of cross bar shapes and sizes up to 3" wide aero bars, the mounts slide in a channel under the rack to match your cross bar set up.
