Thanks everyone, I understand all that. But my original question was about locking up while the rider is on the bike vs. off the bike, i.e. with the suspension somewhere down its travel vs. unloaded and at the top of its travel and how much that affects geometry and handling. On a full suspension bike, for instance, could a rider fine tune the bike's handling by carefully choosing how far up or down their travel he locks out the front and rear shocks?
