O.K. So i'm tryin to get my pnony Phantom rolling,heres the problem!I have one of the centennial Phantom coaster hubs laced to the rear wheel, this hub was a freebie and came w/o a dust cover, snap ring, and sprocket. What the heck fits it? My LBS attempted to hook me up for cheap but the parts don't fit! :? Later & PEACE!!!!
