The Thule TopRide Bike Rack is a rooftop bike rack that is quick and easy to install. The release lever makes it easy to take the bike off the rack, and the quick mounting with visual confirmation ensures that the bike is securely loaded. The Thule AcuTight torque limiter knob clicks when a quick-release bike is securely mounted, making it easy to secure the bike to the rack. The integrated locking system secures the bike to the rack and the rack to the car (two locks sold separately). The adjustable and protective wheel strap holds the rear wheel securely in place, and the easily installable design means that it can be installed on either side of the car. The Thule TopRide Bike Rack is also compatible with carbon frame bikes and bikes equipped with disc brakes. It fits majority of thru-axle and standard 9mm quick release bikes with included adapters, mounts to all Thule rack systems, round bars and most factory racks making it a versatile option for those looking for a rooftop bike rack.
