I think this must be off-topic because it is really quite a heavy piece of kit, but the ad was interesting as it boasted of two speeds and no neutral. Quite true! With dog clutch engaged, you are in one gear and with it disengaged you are in the other. I know that Hilary Stone is fond of the two speed Sturmey; I wonder if he has tried the Villiers.
