Uh-oh again. I feel another winter project coming on. I have ridden the roadster, and the rod brakes don't inspire confidence, clever contraptions though they are. I picked up a coaster brake hub for the rear some months ago. I didn't mean to imply that I thought you should have used the SA dynohub on your Guvnor, Eric. They are quite heavy and the bottle dynamo makes more sense with the tab already on there. Just wanted to make others aware of their existence. The current owners of Sturmey Archer are doing some cool things, but they don't seem put much into marketing.
