Dishing offset number
Hi guys. I am going to use the online spoke calculator found at the Grin Technologies ebikes.ca website in order to find out what spoke sizes I need for my rear hub motor on my 20 inch folding bike. The calculator requires some measurements for the hub motor and I understand most, but don't know how to get the dishing offset number. The number is to be in mm. Does anyone know how to get the dishing offset number?
