A well-tuned suspension is the biggest difference between "rides okay" and "rides great." You can adjust your setup in just a few steps – all you need is a shock pump and a few minutes of your time.
Step 1 – Setting Sag (the basis for everything else)
Sag is the amount of suspension travel that compresses under your weight in a normal riding position.
- Put on your complete riding gear (shoes, backpack, protective gear – just as you ride).
- Slide the rubber ring on the stanchion/cylinder all the way down to the wiper.
- Sit in a neutral position on the bike without bouncing (best to lean against a wall), and carefully get off again.
- Measure how far the ring has moved in relation to the total suspension travel.
Reference values (for orientation):
- Fork: approx. 15–20 % Sag
- Shock (Trail/Enduro): approx. 25–30 % Sag
The model-specific recommendation for your bike can be found in the manual of your model in the Tech Archive. More sag = more comfort and traction, less sag = more support and pop.
Step 2 – Rebound Adjustment
Rebound controls how quickly the suspension extends after compressing. Start in the middle of the adjustment range. Rule of thumb: If you push the bike down hard and let go, it should come back quickly, but without bouncing. Too fast feels nervous/kicky, too slow results in the suspension "bottoming out" on fast hits.
Step 3 – Compression Adjustment
Compression (if adjustable on your model) regulates the resistance when compressing. Start fully open and close in small increments until the suspension provides enough support in corners and when braking, without becoming harsh.
On Rockshox Ultimate, Fox Factory, and all Öhlins models we install, you also have high-speed and low-speed compression, indicated as HSC and LSC. On the respective manufacturer's website or on some models on the fork steerer, you will find a basic setup or tips for adjustment.
Tips:
- Always change only one setting at a time and take a test ride.
- Note your working setup (air pressure, clicks) – this way you can quickly return to it after a service.
- Manufacturers like Fox and RockShox offer setup apps/calculators with baseline values that serve as a good starting point.
Important: Only adjust the air pressure with a shock pump and never exceed the maximum pressures stated in the manual.
