We just purchassed a 2016 Subaru Outback with a factory roof rack. We need to purchase two bike racks. The widest tire (between 4 bikes) is on a Trek 'hybrid' commuter. We would like to know: 1) How the rear end of the Thule Outrider Fork Mount is secured to the car rail (that has no center channel). Would it be a 'gravity' contact using a rubber pad or does the pad form an umovable (with a strap?) attachment? 2) Given the car we'll install these on, do you have an opinion whether one would allow better clearance to open the rear door with the rack and bikes mounted? 3) We're pleased that both the Outrider and the Circuit lock the bike fork to the rack and the bike rack to the roof rack. No matter which rack we choose, we'll need one lock core/rack, correct?
