Geoff: "I am looking for a 17 teeth gear for my Sturmey Archer CS gearbox. O/D is 1.825", width is .5625", centre hole I/D is .750", it has six splines in the centre hole (.8625") and goes on the layshaft which has a six splined section which is just under .8625" O/D to take the gear. I can get some made for £150 each...but I need to order five to get them at this price! So if anyone wants one, let me know (via John)"
