Simple and easy to use, it has been designed such that it doesn’t need to be permanently attached to the roof. A special asymmetric “C” shaped plate holds the roof rack cross bar.
Once the wheel has been positioned, the resin cone-shape member centres the wheel rim hole and the throttle bolt fully tightens against the rod, thus creating a pull-clamping.
This system allows, first, safely positioning the wheel onto the roof rack and then anchor it in the most suitable position to your needs, by using this special clamping system. The metal material used for this accessory is stainless steel.
