If you already own the 2 bike, Thule T2 Pro XT rack and it has a 2" receiver hitch mount, this add-on will turn your rack into a 4 bike rack.
Lock bikes to the rack with the integrated cable lock
Eliminate bike interference by adjusting side to side to create generous spacing between bike mounts
Secure bikes quickly without frame contact with the frame-free ratcheting arm
Ideal for carbon frames, mountain, downhill, ebikes and fat bikes as it fits 20 - 29” wheels and up to 5” tires without adapters
Not for use with front fenders
