The standard silver Roto is a triumph of aspiration over reality. The black version takes the whole delusion a step further. The subtle addition of a highly chromed hanger bolt and black highlights almost gives this copy of the quintessentially mundane Huret Svelto the sheer pizzazz of a Campagnolo Super Record or a Zeus 2000.

It’s a harmless enough dream.
