Öhlins RXF36 m.2 setup
The RXF36 m.2 has two air pressures to set, not one. Put in your weight for Öhlins’ own pair of numbers, then set sag.
Fill the ramp-up chamber to 185 psi first, then the main chamber to 95 psi. Then measure sag.
Rebound, spacers and limits
- Compression: Low-speed: 14–16 clicks out from fully closed, counted from the blue dial (close to fully open). High-speed: position 3 (fully open). Position 0 (fully closed) is a climbing setting, not for normal riding.
- Rebound: Öhlins gives one starting point for every rider weight: 14–16 clicks out from fully closed. The dial has about 15 clicks, so that is close to fully open. Rebound is the gold dial.
- Volume spacers: No spacers. Ramp-up is set by the second (ramp-up) air chamber.
- Fill the ramp-up chamber (lower valve) first, then the main chamber (top cap). Set sag with the main chamber only.

Fix what you feel
Tap what your fork does. Fixes are for your TTX18. Change one thing at a time, then ride the same section again.
Harsh over roots and braking bumps
Too much air, or compression too firm.
- Check sag first. Under 10% of travel means too much air in the main chamber.
- Open low-speed compression 1 click (counter-clockwise).
- Open high-speed compression one position (counter-clockwise). Keep it at 1–3 for trail riding. Position 0 is for long climbs only.
- If it also feels hard and packs down, open rebound 1 click.
Dives under braking and on steep roll-ins
Not enough low-speed compression, or too much sag.
- Close low-speed compression 1 click (clockwise). Öhlins says to do this if the fork feels soft, spongy or unstable going into a corner.
- Still diving and sag is past 15%? Add 3–5 psi to the main chamber.
Bottoms out hard on drops and big landings
Not enough compression, or not enough support at the end of the travel.
- Close low-speed compression 1 click (clockwise).
- Close high-speed compression one position (clockwise).
- Still bottoming? Add 5 psi to the ramp-up chamber (lower valve).
Never uses full travel, even on big hits
Too much air, or too much compression.
- Check sag. Under 10% means too much air in the main chamber, so take some out.
- Open high-speed compression one position and low-speed compression 1 click (counter-clockwise).
- Still short? Take 5 psi out of the ramp-up chamber.
Bouncy, or clunks at full extension
Rebound is too fast.
- Close rebound 1 click (clockwise). Öhlins says to do this if the bike feels loose, nervous or kicks in jumps.
Rides lower and lower through rough sections
Rebound is too slow, so the fork packs down.
- Open rebound 1 click (counter-clockwise). Öhlins says to do this if the fork feels hard, harsh or packs down under bumps.

Full Öhlins RXF36 m.2 reference
For the RXF36 m.2 Air (TTX18 damper, 150–180 mm), from Öhlins’ owner’s manual issued January 2023. The RXF36 m.1 and m.3, and the coil fork, have their own manuals on ohlins.com.
How to fill the Öhlins RXF36 m.2’s two air chambers
Two pressures. Ramp-up chamber (lower valve, runs higher): set this first. Main chamber (top cap): set second. The main chamber sets your sag. Fill both, then measure sag and add or release air in the main chamber only. If you let air out of the main chamber, pull the fork back to full length by lifting the bars with the wheel held down, about 10 times.

Öhlins RXF36 m.2 rebound setting
Öhlins gives one starting point for every rider weight: 14–16 clicks out from fully closed. The dial has about 15 clicks, so that is close to fully open. Rebound is the gold dial. Turn the dial clockwise until it stops, then count the clicks back out counter-clockwise. Push the fork down hard and let go. If it clunks or kicks at full extension, rebound is too fast. If it stays low, it’s too slow.
Öhlins RXF36 m.2 sag in millimetres
| Travel | 10% (firm) | 15% (plush) |
|---|---|---|
| 150 mm | 15 mm | 23 mm |
| 160 mm | 16 mm | 24 mm |
| 170 mm | 17 mm | 26 mm |
| 180 mm | 18 mm | 27 mm |
Worked out from Öhlins’s 10–15% sag range. Measure with the compression adjusters fully open, dressed to ride, weight spread across saddle, bars and pedals.
Öhlins RXF36 m.2 compression settings
| Damper | Start at |
|---|---|
| TTX18 | Low-speed: 14–16 clicks out from fully closed, counted from the blue dial (close to fully open). High-speed: position 3 (fully open). Position 0 (fully closed) is a climbing setting, not for normal riding. |
Öhlins RXF36 m.2 volume spacers
No spacers. Ramp-up is set by the second (ramp-up) air chamber.
The RXF air fork has no volume spacers to count. How hard it ramps up is set by the second air pressure, the ramp-up chamber on the lower valve. Öhlins says to contact an Authorized Öhlins MTB Service Center if you want a more progressive spring.
Which Öhlins RXF36 m.2 damper do I have?
- TTX18: Blue low-speed and black high-speed compression dials on top of the cartridge, and a gold rebound dial.
TTX18 is the only damper on the m.2. It has one dial each for low-speed compression, high-speed compression and rebound.
Öhlins RXF36 m.2 service interval
Öhlins says to service the lower legs every 50 hours, and the air spring and damper cartridge every 100 hours or once a year.
Questions
What air pressure should I run in my Öhlins RXF36 m.2?
Öhlins gives two numbers per rider weight. A 170–180 lb rider sits at the top of the 154–176 lb row (main 90–100 psi, ramp-up 180–190 psi) and the bottom of the 176–198 lb row (main 100–110 psi, ramp-up 190–200 psi). Fill the ramp-up chamber on the lower valve first, then the main chamber under the top cap. Then check sag. Öhlins lists a 120 kg (265 lb) maximum rider weight.
How much sag should an Öhlins RXF36 m.2 have?
About 10–15% of travel, which is 16–24 mm on a 160 mm fork. That is less than the 15–20% most forks use. Öhlins says a hard-charging rider may want less and a smooth rider more. Measure on flat ground without bouncing, dressed to ride. Too little sag: let air out of the main chamber. Too much: add air to it.
How many clicks of rebound on an Öhlins RXF36 m.2?
Öhlins gives one start for every rider weight: 14–16 clicks out from fully closed on rebound and on low-speed compression, with high-speed compression on position 3. After that, change one click at a time. Close rebound a click if it feels loose or kicks. Open it a click if it feels hard or packs down.
Does this work for my older Öhlins fork?
No. These numbers are for the RXF36 m.2 Air with the TTX18 damper. The RXF36 m.1 and m.3, and the coil fork, have their own manuals on ohlins.com.
