Re: Creative Engining! MAnic Mechanic! Jim! PLease HELP!
The flanges range from 2.0" to 2.4". The standard sprocket adapter fits this range of flange diameters.
The Occ hub has larger flange...so for hubs that have flanges larger than 2.4" I use an Occ blank and bore it to the hub size.
The bolt circles are 3.125" for the standard adapter & 3.625" for the Occ.
