They're using a custom tensioner - the pimped one looked to have the stock plastic one. I imagine there is a lot of extra lash in the action, since you have to pull the tensioner straight before the hub changes gear or brakes. I have a real Duomatic 102 (not the modern SA version) but it's on a Raleigh Twenty.Its awful but I think Kinetics make coaster brakes for Bromptons. If they do they will work.
