correct price saw the roof bar cost.
For my part I use to Stand up Paddle transported 2x (a 3m25 and the other 3m00), each weighs 11kilos.
after several travel (highway), the product is simple to you installation.Méfiez the roof of your vehicle, because I carry my boards on an old Volvo station wagon and the roof sheet is thick enough, for cons I made the Test on a 2010 Honda Civic and the roof sheet metal has sunk, I have the pus recovered but it is really fine .... So on a recent drive, I'd say no more than 10 kilos if you do not want crumpling the sheet ....
