Re: My recent find (Vitus 979) any help to identify age than
With the grub screw fixing I would say late 80's at least. Mine is a 1986 and has the conventional style. You should be able to find a date stamp on one of the cast parts of the frame somewhere, possibly the BB shell or the seat lug area? Mine definitely has either 86 or 1986 on it but can't remember exactly where and it's tucked away in the attic at present so can't check. There should also be stampings/mouldings to say what size it is.
I like mine, it's a very nice ride.
