My Right rear wheel rubbing...

What type of wheel setup is on the rear? Have you made sure the wheels are the same offset? The two rallyes on the back of my demon are about 1/4” difference. Im using sbp to lbp adapters in the back anyway, one side uses a 1” adapter while the other side is a 3/4” adapter and both sides are the same distance from the springs, the one odd backspace wheel even has the valve stem set in farther, one side my cap protudes the beauty ring and the other side is almost flush but sticks out a hair past the beauty ring. Just a thought
