is englisg threading compatible with ISO track hub
im building a fixed gear from a 1920s track frame (it is skip tooth) and i need some advice on the rear hub. i have a fixed/fixed (double sided) origin8 rear hub that i had planned to attach a 8t skip tooth cog. it is english threading and from what i gather the difference is 1.375 as to 1.370. i thought that was fine but a bikeshop at my house swore that a skip tooth cog would not be compatible with the hub soo.....
help me out, i could use some input
