I have a question about a rear shock for one of my bikes. how can you tell if the rear shock is charged or not? Is there a pressure we should be running (schrader valve) and if so seems there are tires shops filling tires with nitrogen now will they be able to put enough pressure in one? I am not too cheep but have 10 bikes and it sure gets expensive when changing pistons or shocks or rebuilding forks! Any real advise would be welcomed!
