The Dacia modular roof rails / bars (the type that adapt from fitting lengthways to across the roof) sit very close to the roof, and are wider and deeper than most cross bars, so many roof mounted accessories are not compatible. We do have a range of bike carriers by Yakima that will fit Dacia Modular bars:
Yakima black HighRoad Extended 9812150
Yakima silver HighRoad 8002128 (roofbox.co.uk
Yakima black HighSpeed Extended 9812151
Yakima silver HighSpeed 8002129 (roofbox.co.uk)
