Rhino bars are deeper than most roof bars, because of this not all bike carriers come with fittings that work with these bars. The Yakima HighSpeed and HighRoad will fit both Rhino Delta and KammBars:
Yakima silver HighRoad 8002128 and Yakima black HighRoad Extended 9812150
Yakima silver HighSpeed 8002129 and Yakima black HighSpeed Extended 9812151
