I'm looking for BOB Nutz that will fit this 9mm Sturmey Archer axle. Any help would be greatly appreciated. Thanks!
Something doesn't smell right here. The data sheet is calling that axle 9mm, but 9mm rear axles don't really exist. They would have awkward up and down slop in the dropout. I think what's going is that it's a 9.5mm x 26tpi thread (same as 3/8"x26) and for whatever reason that data sheet is calling it 9mm. (It could also be 24tpi, but that size never really goes along with freewheels, only coaster/IGH.) Note that Sturmey is Sunrace and this kind of thing does happen in documentation.
There are some more or less antique bikes that use smaller size rear axle diameters, but I don't think that's what this hub is for.
Edit: Here is a wholesaler (where shops and dealers would look to confirm compatibility before buying) listing this as a 3/8" axle hub.
