Seat Stay Design


Work in progress!  Please be patient.

This is as best we know a chronological view of the design of the tops of seat stays at the seat lug.  Please send in your further examples.  The type numbers will change as we introduce more variations.

Type 1

1948-9 Viking Master SSShown here on a 1948/9 Master SS.  To date only seen on this model.  The pointy end may be a part available to other manufacturers because it, or something very similar, has been seen on other brands of frames (but some of these might have come out of the Viking factory? – there is no question that some Viking frames were re-branded but we have no information on when this started)



Type 2

1950MasterSS (2)Shown here on a 1950/51 Master SS.  Also seen on Ian Steel’s 1951 Tour of Britain winning bike, and a frame that may be an early Tour of Britain or that may be an anomalous Severn Valley with Nervex Professional lugs (There is a discussion of this frame HERE (to be added))





Type 3

Early_SV_Seat_ClusterThis is on one of the first generation of Severn Valley frames (an early one with the rectangular brass head badge – likely 1950/51).  We do not currently have any other examples of this design and have not inspected this very closely to ascertain whether it is a brazed-on plug or cap or whether it is formed out of the stay tube – it looks as if it could be either from this photograph.



Type 4

1952/3 Tour of Britain SN 734This semi wrap over design was the staple of Viking’s top level race frames (Severn Valley and Tour of Britain) until superseded in 1957.






Type 5 plus (many to be inserted prior to this)

1957on SV Seat Cluster Sorry about the cord in this picture – this image will be replaced as soon as we have a better one.  This is the classic identifier of Severn Valley models built with Nervex Pro lugs from 1957 onwards.  There are some post-1957 “Severn Valleys” with different seat stay tops, but we have yet to be convinced that they are not Mileater or Grand Tour models (both built with Nervex Pro lugs) that have been reassigned as Severn Valleys – but as with all things Viking, anything is possible
