Tubus racks are either brazed with Chromoly steel tubing or welded with stainless steel tubing. The Chromoly racks are very strong and durable, and lightweight. The stainless steel racks (Cosmo and Luna) are heavier and have lower maximum load capability since stainless steel is not as strong as Chromoly steel. But they look awfully nice, and they won’t rust. The rear racks are all triangulated. If you view them from the rear, all the struts on the “Fly” and “Luna” and the center struts on the “Cargo” and “Cosmo” angle inward toward the top, making for an extremely stiff structure.
