40 Hole spoke set to fit 19" Rear rim and Norton cotton reel hub, as used on all Rigid, Swinging Arm (ES2, Mod50, Dommie) and roadgoing Featherbed International hubs (the type with equal flange diameters. The dimensions are taken from my own wheels.
This listing is for a galvanised spoke set to fit a 19" rim to the Norton 'Cotton Reel' type hub, as fitted to most rigid framed rear wheels, as well as those most commonly fitted to all swinging arm and featherbed (none Manx) models rear wheels, up until the introduction of the full width hub in the late 1950's. This 3 stud hub was also used on all pre-war non-Inter front wheels, so this spoke set should fit that type of wheel as well, providing you wish to fit it to a 19" rim. This hub is identified by having equal diameter spoke flanges
However, although the 'Cotton Reel' hub has equal spoke flanges - the original Norton spokes for this type of hub with a 19" rim had slightly different spoke lengths - to allow for the slight offset of the rim, that this type of wheel was always built with (to allow for the brake drum always fitted to this type of hub - wether fitted on the front on pre-war bikes, or rear for pre and postwar rears). Some Spare Parts list (i.e. the 1937 WD 16H Spare Parts List) may show the spoke length as being equal - but in reality, one side was fractionally longer than the other - Norton's probably cut them on one side once laced to a rim.
We have replicated the lengths of these spokes to the same length as two genuine amd original Norton 'Cotton Reel' Hubs/rims - still fitted with their original Norton spokes, so we know these lengths are definitive for this type of hub. The longer spoke fits on the non-drum side (i.e. the rim is normally closer to the hub) . . . but you need to adjust the rim to suit the bike model you are fitting it to - the fim should always be centralised in the frame or forks once fitted with all spacers and drum.
Note: Plunger hubs have flanges of slightly different dimensions - email us if you want spoke sets for this model. These are good quality UK manufactured 9 gauge galvanised spoke and nipple sets.
