Yakima SweetRoll car top kayak carrier. Fits round, square and aero type bars. Wheels on rear pads for easier loading. Bought this here in the FM some time ago in anticipation of buying a kayak but then went with a SUP instead. Comes complete with all straps, clips, adapters, etc. $100 net to me (cash, picked up price in Concord NC), will take to UPS store for boxing/shipping & PayPal fees on your dime.
