The Thule Wing Bars are smoothly curved to help create an aerodynamic edge which helps to the bars carve through the air with ease.
Compared to other roof bars this gives you a much quieter ride while also reducing fuel consumption at the same.
All Thule's Wing Bars are equipped with a full width T-Track, this helps to simplify the changing of load accessories.
So if you are changing from a bike carrier to a ski carrier, this feature allows you to change without a worry. Simply slide in and attach the new accessory. You can use the entire length of the Wing Bar, to make maximum space for several accessories on the car roof.
