Today I received a 26" rear wheel with 12 gauge spokes as an improvement over my stock 14 gauge spoke wheel. To my dismay the flange is too big for the stock sprocket and rubber mount nine-hole setup. It also appears as though the bolts would just barely fit between the spokes even if the flange were smaller. Could anyone here point me to a sprocket adapter which would fit my wheel. No, I don't have a coaster brake hub. The actual hub is cylindrical with an approximate 5/8" diameter.
