Q. What is the difference between standard & aero bars?

A. Thule manufacture two different types of bar, the standard and the aero. The key differences between these two bars are the material, shape and the way that Thule accessories (such as bike or kayak carriers) are mounted upon them.

The standard bar is manufactured from stainless steel, which is then plastic coated to protect the metal. Accessories generally attach to the standard bar by clamping around it.

The aero bar is manufactured from aluminium and is consequently much lighter, it does not have a plastic coating. The aero bar is ovalised to make it more aerodynamic (hence the name) and this cuts down on wind noise and improves fuel economy (if you are planning on leaving your roof rack on your car all the time). Accessories often attach to the aero bar by utilising its T-track; a slot which runs the length of the top of the bar, which will accept a bolt shaped like an upside down "T", accessories then screw down on to this bolt. The aero bar is a little more expensive than the standard bar.

Q. My Vehicle is not listed?

A. Unfortunately if your vehicle is not listed in the selector for either Roof Bars or Rear Cycle Carriers then Thule do not make a roof rack/cycle carrier for you vehicle. This is often the case with older cars, imports and convertibles.

For cycle carriers it might be worth looking at a tow ball mounted carrier.

Q. What are roof rails?

A. Roof rails are generally factory fitted bars that run from the front to the back of a vehicle's roof. They are commonly found on estate, 4x4 and SUV vehicles but whether they are present or not depends on your car's manufacturer and model.

If you do have roof rails then you will find a roof rack is typically a little less expensive and quicker and easier to fit.

Q. How long does it take to fit Thule Roof Bars?

A. Once a Thule roof rack is fully assembled most people can manage to fit/remove their roof rack in less than ten minutes (even quicker if your car is fitted with roof rails). Allow approximately half an hour for initial assembly and fitting.

Q. My car has a spoiler, can I fit a rear mounted bike rack??

A. Unfortunately, vehicles fitted with boot spolier are not able to carry bikes using a rear mounted bike rack. Instead you will need to use a roof mounted or tow bar mounted cycle carrier
