Just refurbed this old Claud Butler. Went with tubulars, Schwalbe One, oh my they have a nice ride. Took it out on its maiden voyage a couple days ago and my riding buddy remarked, "Your bike is so quiet". It really is. And everything seems "tight ". Some of the more unusual components... Zeus Criterium crankset, Huret Svelto derailleur, early GB stem, and my fave Wrights saddle which is a survivor from a '69 Raleigh Grand Prix.
