RockShox Domain setup
Most Domains leave the shop set for someone else. Put in your weight for your starting pressure, straight from RockShox’s own chart.
Pump to 58 psi, then measure sag and adjust.
Rebound, spacers and limits
- Compression: RockShox gives no starting point for Isolator. Fully open is counterclockwise, Lock is clockwise.
- Rebound: RockShox does not print rebound clicks in its manuals or spec sheets. It sends you to RockShox Trailhead (trailhead.rockshox.com) for the starting rebound for your fork. While you set air pressure, RockShox has you turn rebound fully open (counterclockwise), then set it to the Trailhead number afterward. No Trailhead number? Start open, ride, and add damping a click or two at a time until the front wheel stays planted without bouncing. More air or more tokens speeds rebound up, so add damping after either.
- Volume spacers at 160 mm: ships with 2, max 3.
- E-bikes add 10 psi.

Fix what you feel
Tap what your fork does. Fixes are for your Isolator RC. Change one thing at a time, then ride the same section again.
Harsh over roots and braking bumps
Too much air, too much compression, or rebound too slow.
- Check pressure against the chart for your weight first. Well above it means too much air.
- Open the compression dial 1–2 clicks (counterclockwise).
Dives under braking and on steep roll-ins
Not enough low-speed compression, or too little air.
- Add compression 1–2 clicks (clockwise).
- Still diving? Add about 3–5 psi.
Bottoms out hard on drops and big landings
Not enough high-speed compression, or the spring does not ramp up enough at the end.
- Add one Bottomless Token. Low-speed compression does little on big hits.
- Stay within RockShox’s max token count for your travel (3 on every travel).
Never uses full travel, even on big hits
Too much air, too many tokens, or too much compression.
- RockShox says the fork should reach full travel at the right pressure. Let out about 3–5 psi and ride it again.
- Pressure already on the chart? Remove one Bottomless Token.
- Open the compression dial 1–2 clicks.
Bouncy, or the wheel pogos off bumps
Rebound is too fast.
- Add rebound damping 1–2 clicks (clockwise).
- Just added air or a token? Both speed rebound up, so add a click.
Rides lower and lower through rough sections
Rebound is too slow, so the fork stays compressed.
- Open rebound 2 clicks (counterclockwise).
- If it still sits low, check pressure against the chart and add air.

Full RockShox Domain reference
For the 2025-and-newer Domain (Domain Gold, DebonAir air spring, Isolator RC or Isolator R damper). RockShox’s 2025, 2026 and 2027 sheets match. Pressure depends on travel: 130–150 mm runs about 8 psi higher than 160–180 mm. RockShox’s 2024 sheet lists the older Domain with different travel groupings (150–160 and 170–180 mm), so use your year’s sheet at sram.com/service if yours is 2024 or older.

RockShox Domain rebound setting
RockShox does not print rebound clicks in its manuals or spec sheets. It sends you to RockShox Trailhead (trailhead.rockshox.com) for the starting rebound for your fork. While you set air pressure, RockShox has you turn rebound fully open (counterclockwise), then set it to the Trailhead number afterward. No Trailhead number? Start open, ride, and add damping a click or two at a time until the front wheel stays planted without bouncing. More air or more tokens speeds rebound up, so add damping after either. Turn the rebound dial clockwise for more damping (slower return) and counterclockwise for less (faster return). Fully counterclockwise is fully open. Push the fork down hard and let go. If the wheel pogos off the ground or the bars kick up, rebound is too fast. If the fork stays low through back-to-back bumps, it is too slow.
RockShox Domain sag in millimetres
| Travel | 20% (firm) | 30% (plush) |
|---|---|---|
| 130 mm | 26 mm | 39 mm |
| 140 mm | 28 mm | 42 mm |
| 150 mm | 30 mm | 45 mm |
| 160 mm | 32 mm | 48 mm |
| 170 mm | 34 mm | 51 mm |
| 180 mm | 36 mm | 54 mm |
Worked out from RockShox’s 20–30% sag range. Measure with the compression adjusters fully open, dressed to ride, weight spread across saddle, bars and pedals.
RockShox Domain compression settings

RockShox calls them Bottomless Tokens. They change how hard the fork ramps up at the end of its travel, not its pressure. Add one if you bottom out, remove one if you never get near full travel. Adding tokens can speed rebound up, so add a click of rebound damping after.
Which RockShox Domain damper do I have?
- Isolator RC: Domain RC. One compression dial on top of the right leg and a rebound dial at the bottom of the right leg.
- Isolator R: Domain R. No compression dial at all, only a rebound dial.
Domain RC has the Isolator RC damper (rebound plus one compression dial) and Domain R has the Isolator R damper (rebound only). The R comes in 150–180 mm, the RC in 130–180 mm.
RockShox Domain service interval
RockShox’s Domain service manual describes a 50-hour lower leg service and a 200-hour seal service. For the full schedule, see its other forks’ 50 and 200 hour intervals.
Questions
What air pressure should I run in my RockShox Domain?
Start from RockShox’s chart for your weight with gear. A 170–180 lb rider starts at 54–62 psi on a 160–180 mm Domain and 62–70 psi on a 130–150 mm Domain. E-bikes add 10 psi. Never go over 148 psi. RockShox has you fill to 50% of that, cycle the fork slowly to 25% travel five times, fill to 100%, cycle five more, then top up to 100% again.
How much sag should a RockShox Domain have?
RockShox’s manual says to set DebonAir pressure from its chart and does not publish a sag target for the Domain. Its general guide for air forks is 20–30% sag, which is 32–48 mm on 160 mm of travel. Measure with the dampers fully open, dressed to ride, weight spread across saddle, bars and pedals.
How many clicks of rebound on a RockShox Domain?
RockShox does not publish a rebound click count. Its manual points to RockShox Trailhead for the number for your fork. Set rebound fully open while you set pressure, then use that number, and add damping if the fork feels bouncy.
Does this work for my older RockShox Domain?
Only if it is a 2025-or-newer Domain. RockShox’s 2024 sheet groups travel differently (150–160 and 170–180 mm), so a 160 mm Domain from 2024 or earlier runs different pressure. Use your year’s sheet at sram.com/service.
