This Hardware kit allows the RockyMounts Tandem Mount R4 rooftop bike rack to be mounted to a T-track/slotted crossbar found in Audi®, VW®, Mini®, BMW®, Volvo®, Porsche®, RockyMounts®, Ouray, Thule® Aeroblade, Yakima® Whispbar, etc.
Customizing or downsizing of this kit is not available. Tandem Euro Hardware Kit sold in full only.
Note: Many slotted crossbars are narrow and do not stick out past the towers. When you try and pivot the R4, your Tandem's chain rings may hit the side of the car negating this feature. The R4 will hold your tandem on these bars, but you may lose the pivoting feature.
