RockShox Reba setup
The new Reba has one air pressure, one rebound dial and a lockout lever. Pick your travel and weight for RockShox’s own starting pressure.
Pump to 97 psi, then measure sag and adjust.
Rebound, spacers and limits
- Compression: Lever on Open to start. Lock is for climbs and smooth road.
- Rebound: RockShox doesn’t print a rebound click number in its manual or on the spec sheet. Its recommended starting setting is in the free RockShox TrailHead app (trailhead.rockshox.com, needs a login). Without it, fully open the dial and close it a few clicks at a time until the fork stops pogoing back after a hard push.
- Volume spacers at 100 mm: ships with 2, max 3.
- E-bikes add 10 psi. 120–130 mm forks max out at 160 psi.

Fix what you feel
Tap what your fork does. Fixes are for your Isolator RL. Change one thing at a time, then ride the same section again.
Harsh over roots and braking bumps
Too much air, or rebound too slow.
- Make sure the lockout lever is on Open. Lock is for climbs and smooth road.
- Take out 3–5 psi and ride it again.
- Rebound dial a couple of clicks counter-clockwise if the fork feels like it’s stuck low.
Dives under braking and on steep roll-ins
Not enough air for your weight.
- Add 3–5 psi.
- This fork has no compression dial, so air pressure is your main fix.
Bottoms out hard on drops and big landings
The air spring runs out of support at the end of the travel.
- Add one Bottomless Token. Stay within the maximum for your travel.
- Still bottoming? Add 3–5 psi.
Never uses full travel, even on big hits
Too much air, or too many tokens.
- RockShox says the fork should reach full travel at the right pressure. Take out 3–5 psi.
- If you added tokens, take one out.
Bouncy, or clunks at full extension
Rebound is too fast.
- Turn the rebound dial 1–2 clicks clockwise.
Rides lower and lower through rough sections
Rebound is too slow, so the fork packs down.
- Turn the rebound dial 2 clicks counter-clockwise.

RockShox Reba rebound setting
RockShox doesn’t print a rebound click number in its manual or on the spec sheet. Its recommended starting setting is in the free RockShox TrailHead app (trailhead.rockshox.com, needs a login). Without it, fully open the dial and close it a few clicks at a time until the fork stops pogoing back after a hard push. Turn the rebound dial clockwise for slower rebound, counter-clockwise for faster. Counter-clockwise until it stops is fully open. Push the fork down hard and let go. If the wheel pogos back up, rebound is too fast. If the fork stays low and doesn’t come back for the next bump, it’s too slow.
RockShox Reba sag in millimetres
| Travel | 10% (firm) | 20% (plush) |
|---|---|---|
| 100 mm | 10 mm | 20 mm |
| 110 mm | 11 mm | 22 mm |
| 120 mm | 12 mm | 24 mm |
| 130 mm | 13 mm | 26 mm |
Worked out from RockShox’s 10–20% sag range. Measure with the compression adjusters fully open, dressed to ride, weight spread across saddle, bars and pedals.
RockShox Reba compression settings
| Damper | Start at |
|---|---|
| Isolator RL | Lever on Open to start. Lock is for climbs and smooth road. |
| Motion Control | Lever on Open to start. Lock is for climbs and smooth road. |
RockShox Reba volume spacers
| Travel | Ships with | Max |
|---|---|---|
| 130 mm | 0 | 2 |
| 120 mm | 0 | 2 |
| 110 mm | 1 | 3 |
| 100 mm | 2 | 3 |
These are Bottomless Tokens. They change how hard the fork ramps up at the end of its travel, not its sag. Add one if you bottom out, remove one if you never reach full travel.
Which RockShox Reba damper do I have?
- Isolator RL: Reba Gold. A lockout lever with Open and Lock, plus one rebound adjuster.
- Motion Control: Reba RL. A lockout lever with Open and Lock, plus one rebound adjuster.
RockShox’s spec sheet lists Isolator on the Reba Gold and Motion Control on the Reba RL. Both are RL forks: rebound and a lockout lever, no compression dial.
RockShox Reba service interval
RockShox says to clean and check air pressure every ride, do a lower leg service every 50 hours, and a full lower leg, damper and spring service every 200 hours.
Questions
What air pressure should I run in my RockShox Reba?
Start from RockShox’s chart for your riding weight and travel. A 170–180 lb rider is in the 160–180 lb row: 90–104 psi at 100–110 mm, or 86–100 psi at 120–130 mm. Max is 165 psi (100–110 mm) or 160 psi (120–130 mm). Then check sag.
How much sag should a RockShox Reba have?
RockShox’s manual says 10–20% suits shorter-travel bikes and 20–30% longer-travel ones. For a trail Reba, 15–20% is a good target: 15–20 mm on a 100 mm fork, 18–24 mm on 120 mm. Set the rebound dial fully open first, then measure dressed to ride. More air means less sag.
How many clicks of rebound on a RockShox Reba?
RockShox doesn’t publish a click count. Its starting setting for your weight is in the TrailHead app. Clockwise is slower, counter-clockwise is faster. If the wheel pogos back up after a hard push, close it a couple of clicks. If the fork stays low, open it.
Does this work for my older Reba?
No. These numbers are for the 2026-and-newer 35 mm Reba Gold and Reba RL. Older 32 mm Rebas have their own tables in their year’s spec sheet at sram.com/service.
