Öhlins TTX22M.2 - Yalla! Setup Guide

Basics

Here are a few basics about spring-rate, sag and parameters that determine the spring rate you need.

  • The rate of the spring you use in your TTX22M shock defines the amount of sag.
  • Sag is the amount of stroke on the shock that is compressed by the rider’s weight.
  • A higher spring rate 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 the high speed and low speed compression.

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.

HSC – High Speed Compression

Large impacts hitting the rear wheel fast are absorbed by the spring and can be slowed down by the high-speed compression damping. Adding HSC damping will slow down the suspension when being compressed by a large impact.

LSC – Low Speed Compression

Small impacts hitting the rear wheel are absorbed by the spring and can be slowed down by the low-speed compression damping. With no LSC damping, the spring will be able to absorb every little impact and track the ground very precisely. By adding LSC, you can make your suspension use less travel on small impacts, which can make the suspension a bit calmer on small impacts.

LSR – Low Speed Rebound

The rebound damping defines how fast the suspension extends after absorbing an impact. More rebound damping means that the suspension extends slower. If it extends too slow, it might not be ready for the next impact. A compressed shock is holding the energy from the impact, so if your rebound is too fast, you will get the energy right back to your feet, making the bike hard to control.
