The bin shoot looks like it didn't help matters ,
So did Layher and Rux. They both had frame systems, specially GKN Kwikform in the early 90's that adopted the Layher frames. They looked a bit flimsy but ok when they were tied properly.Jap frames used a lot in Asia, Australia etc, Germans had a version which was copied by SGB back in the 90's they called it Sprint.
