Re: O/T Sturmey Archer gears

Hi John, Putting my Vintage Bike collectors hat on, as far as I know the only Sturmey with 2 control cables was the S5 5 speed. A later variety had only one cable. I have the maintenance info for all the earlier gears but the S5 came o/s my interest.

SA did 3,4,5 and 7 speed hubs. They had a prototype 8 speed out when Sun Race bought them out.

AFAIR the neat thing about the 2-speed conversion on the SA was that it was almost all standard parts. This is going back nearly 30 years, & it was far from new then, but my recollection is that the (standard) input sprocket on the SA hub was offset, on some sort of spline & held in place with a circlip. The conversion managed to fit two standard sprockets back-to-back, with a more or less standard Cyclo/Benelux shifter, & I suppose the hub was bulit into a specially dished wheel. Any spares needed could be supplied by any decent cycle shop of the day. ISTR seeing these things advertised in my schooldays ( maybe in Meccano magazine? ), but the one I had was the only example I actually saw in reality.

Well worth pulling some to bits Tim. They use 32 DP gears, the same as the metric ones on the CVA
