Just a warning to those that purchased the aero cross rails that fit onto the SSD racks. I noticed that they are attached with very little reinforcement. I originally over tightened them and when I took them apart I noticed that the screw was held in by a small steel pin inserted into plastic. I mentioned this to SSD requesting a new one but never got a reply. Well today I lost my new Kayak on the freeway when the wind ripped it and the crossrails right off my racks. They may have a good weight limit but theres no sign of pull force to those racks. Going to look for a new tower mount system. Does anyone have any recommendations for a solid tower crossrail system?
