Formula MOD - Jibb Setup Guide
Here are a few basics about sag and the parameters that determine the air pressure you need.
- The amount of air pressure you use in your Formula MOD shock defines the amount of sag.
- Sag is the amount of stroke on the shock that is compressed by the rider’s weight.
- More air pressure will result in less sag.
Defining Your Spring Rate
Defining the spring rate that fits you, depends on a few factors.
- The spring rate depends on the design of the suspension. The same rider will need different spring rates on different bikes. You cannot simply transfer the spring rate from bike A to bike B.
- The spring rate mainly depends on the rider’s weight. The weight should include all gear you wear.
- Your riding style also influences the spring rate that fits you best. Choosing a firmer spring (higher rate) will result in less sag, which means:
- You will effectively use less travel
- The geometry of the bike will be a bit more ‘up-right’, with a little higher BB
- The chance to bottom out is smaller
- Choosing a softer spring (lower rate) will result in more sag, which means:
- You will effectively use more travel
- The geometry of the bike will be a bit more ‘slack’, with a little lower BB
- The chance to bottom out is bigger
The compression damping and the rebound damping are also very important in setting up the shock correctly. If for example you are a racer and have a very aggressive/ efficient riding style, you might want to go up in spring rate, but you can also play with compression damping.
It is recommendable to have a few different spring rates in your toolbox. This way you can change your sag depending on the gear you wear, the type of terrain you ride and simply how you feel.
These are spring rates we recommend, with a basic setting for the four damping settings. The number of clicks is counted from fully closed.
