3-2. Coil over shock.

The drawing below shows a coil over type rear shock (Pro Deluxe made by RockShox).

The shock has a pre-load spring to set “SAG” and external knobs to control compression and rebound
settings. The shock has a knurled pre-load adjustment ring to ”pre-load” the spring.

Different riders require different performance characteristics from their suspension.
A. Heavier riders need a stiffer spring and more compression damping.
B. Lighter riders need a softer spring and lighter compression damping.

Below is a chart showing the standard spring rates, and the recommended spring rates for different
weight riders.
