I have this rear wheel on my fiances bike that slips when under power. it doesn't do it all the time but does slip for some reason even when just cruising and not from a stop to start. the wheel is a schwinn S2 i believe and the hub only says germany on it. The brake arm says Schwinn Approved. I took apart the hub and this is what I have...
