Found a lovely Suntour 13-26 6 speed freewheel last night to replace the Shimano HG 14-28 as my little Huret Svelto does not like the 28... will also be installing some Marathons to replace the Ultra Sports as I find them to be the most dependable tyre and have some in a 27 inch size.
Ran into a fellow with an 83ish UO4 yesterday... Canadian made model with no chrome on the forks and Sachs Huret running gear... it was in pretty minty shape and he said he just loved it.
Said he bought it at the last police auction and am guessing he got it for pocket change.
