Whats the deal with the valve stem on coys? any pics???

It's placed directly in line with the rotor,so you have to use the flat valve stems with disc brakes. These valve stems require a special inflation tool and are notorious for leaking. I can tell you from personal experience with 13" brakes and 18" wheels that you have to remove the wheel to put air in the tire because the inflation tool is to long to get a tire chuck between it and the rotor.
