You asked about loads. Neither my support nor Thierry's add anything for weight capacity, nothing significant, anyway. It's about stability. I would say some extra stability/support is needed if you either get the larger version of the Tsukayu bags or if you mount either size of Tsukayu bag with EasyBrackets. The farther out you "hang" the load, the more it can "wobble" and the more stress on the bolts.
Of course the irony of needing a bolt-on support to stabilize EasyBracket-mounted bags is not lost on me. So much for "quick-disconnect." This is obviously not a problem for most Tsukayu bag owners.
