How can I adjust mountain bike shocks effectively?

To adjust mountain bike shocks effectively, first identify the type of shocks on your bike (air or coil). For air shocks, adjust the air pressure to match your weight and riding style. For coil shocks, adjust the preload to achieve the desired sag. Fine-tune the rebound and compression settings based on the terrain you're riding. Experiment with different settings to find the optimal balance of comfort and performance.
