Keep in mind that the ADV (anti-dive valve) has a purpose which is to prevent the front springs from compressing too much under hard, Emergency "REAR" braking.

Another "Rough Ride" solution is to not ride the rear brake on a rough road. If the ride is STILL rough when NOT using the rear brake then the ADV plunger is stuck and needs to be repaired...Which costs money...Or a person could just disable the plunger with a shim.
