Looking at a Sturmey Archer indicator chain I need to replace - several are listed in various online catalogs - Mark I, II, III, etc, more than one "compatible with AW". My hub in a 80s vintage AW (3-speed steel body), axle seems to be about 152 - 154 mm (? - hard to tell without removing wheel). The indicator rod itself ("spindle") is 51mm (2") total length from end of point to end of clevis, there are 6 marks on the rod. There are 4 pin (outer) links and 3 roller (inner) links in the chain. Total length of assembly is 118 mm.
Any ideas which version I need? Are all indicator spindle rods the same length? If so, the length of the chain doesn't matter if the chain is a little too long.
Thanks in advance... -w
