##Thule 972 HangOn 3 Bike Towball Carrier Thule’s 972 HangOn Towball Carrier can carry 3 bikes safely and securely on the back of a car, keeping them out of the way of the wind, insects and low-hanging car park barriers. There is no need to remove the rack to access the boot either as it can be tilted out of the way when not loaded up with bikes. Soft rubber straps clamp over the top tube to hold the frame and the additional strap can be used lower down to ensure that there is no movement. When not in use the rack can be folded down for easier carriage or storage.
