I want to remove the rear wheel in order to replace the tire and tube.
How to detach the chain-tension cable on this old-school 3-speed Brompton? Does that black losenge-shaped thingie that is attached to small chain going into the rear hub simply get twisted off the threaded connector? Is that shiny clip somehow involved?
When I attempt to unthread the plastic piece from the threaded connector at the end of the hub chain, the chain-tension cable itself begins to untwist into separate strands.
