Yakima EXO Double UP/EXO system bike mount

This system is brand new and is still in the box. I sold my bikes, so I don’t need the system. I paid over $800 for it last summer. Only compatible with the Yakima EXO system. The two-bike EXO DoubleUp attaches directly to the EXO SwingBase or the second tier EXO TopShelf allowing room for an EXO GearLocker or EXO GearWarrior below. Accommodates anything you’re riding — fat tires to road bikes and everything in between.
