The Huret Svelto design - but with added Italian charm. Everything is slightly nastier from the chrome to the pressings, but dig those groovy drilled pulley cage plates and badly cast aluminium parallelogram plate.

Its worth noting that without the hanger plate this Roto weighs 175g - a seriously competitive weight that is well into titanium territory!
