How it compares
On travel, the Specialized Demo 11 is right where the “downhill bike” category usually is: 200 mm up front against a median of 200 mm from 16 bikes. Front and rear both work with 200 mm of travel. No other Specialized model among its mountain bikes has more travel up front. The frame is made of carbon.
With a starting price of €12,499 (S-Works), the Specialized Demo 11 is above the category median (€7,100). The top build, S-Works LTD, costs €13,499. Depending on the build, fork and shock come from RockShox and Öhlins. The fork line-up ranges from the RockShox BoXXer Ultimate to the Öhlins DH38 m.2 Air TTX18. The S-Works build uses a coil shock (RockShox Vivid Coil Ultimate DH), so SAG is set with the spring rate rather than air pressure.
Setup notes for this spec
- Air fork (RockShox BoXXer Ultimate): the air valve is on top of the left leg under a cap. Change pressure in small steps (about 5 psi (0.34 bar)) and cycle the fork a few times afterwards so the air chambers can equalise.
- Rebound: on RockShox suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
- Coil spring (RockShox Vivid Coil Ultimate DH): if SAG is off, only a different spring rate will fix it. Preload should just keep the spring from rattling; more preload makes the shock less supple.
Target SAG for the Specialized Demo 11
SAG is the share of travel your weight already uses in the riding position. The table gives it straight in millimetres – read the O-ring on the stanchion and on the shock shaft and adjust the air pressure until it matches. Any figures from Specialized take priority.
200 mm fork, 75.0 mm shock stroke (all builds)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 34 mm | 24 % = 18.0 mm on the shock shaft |
| Trail | 20 % = 40 mm | 28 % = 21.0 mm on the shock shaft |
| Enduro / rough | 22 % = 44 mm | 30 % = 22.5 mm on the shock shaft |
| Bike park | 20 % = 40 mm | 27 % = 20.2 mm on the shock shaft |
How to measure SAG is explained in our guide SAG setup.
Tyre pressure starting values
For 2.40″ wide tyres, tubeless with a trail casing. With an inner tube about 0.2 bar (2.9 psi) more, with an insert about 0.1 bar (1.5 psi) less. Stock tyres: Cannibal 2.4; S-Works Cannibal 2.4.
| Ready-to-ride weight | Front | Rear |
|---|---|---|
| 60 kg | 1.43 bar (21 psi) | 1.63 bar (24 psi) |
| 70 kg | 1.55 bar (22 psi) | 1.75 bar (25 psi) |
| 80 kg | 1.67 bar (24 psi) | 1.87 bar (27 psi) |
| 90 kg | 1.79 bar (26 psi) | 1.99 bar (29 psi) |
| 100 kg | 1.91 bar (28 psi) | 2.11 bar (31 psi) |
| 110 kg | 2.03 bar (29 psi) | 2.23 bar (32 psi) |
| 120 kg | 2.15 bar (31 psi) | 2.35 bar (34 psi) |
Air pressure in the fork and shock
The sticker on the fork (or on the shock) and the manufacturers’ setup charts give you a first pressure. Our calculator is more precise and suggests rebound too – always check the result via SAG.
