a sproader(rear drive sprocket and disc brake in one) for a bicycle? I'm sure it would not be easy because lack of clearance with the spokes but I know it would be very cool! Love to see or buy one...
"King's Sales & Service Group (A.K.A. King's Sales & Service) is proud to announce the arrival of its revolutionary new Top Hat Sprocket Adapter. The Top Hat Sprocket Adapter precision mounts the rear sprocket onto any ISO standard 6 bolt disc brake hub AND helps to put the sprocket in the proper location to help ensure a perfect chain line!
