How it compares

110–120 mm at the fork almost exactly matches the 120 mm median of the 23 bikes in the “cross-country full-suspension bike” category in our database. On travel, it slots in between the Specialized Epic Hardtail and the Specialized Stumpjumper 15 in the Specialized range. Specialized builds the frame from carbon.

The starting price of €4,199 (Sport) is roughly in line with the category median (€4,350). The top build, S-Works LTD, costs €15,499. Specialized uses RockShox suspension throughout. The fork line-up ranges from the RockShox Reba to the RockShox SID SL Ultimate.

Setup notes for this spec

Air fork (RockShox Reba): 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.
Shock (RockShox SIDLuxe Select+): get on the bike in your normal riding position, step off carefully and read the O-ring. Always cycle the shock a few times after pumping.

Target SAG for the Specialized Epic 9

The table converts the recommended SAG percentages into millimetres, so you can check them with the O-ring directly on the stanchion and on the shock shaft. Adjust the air pressure until the value is right. If Specialized specifies its own target SAG for your model, that takes priority.

120 mm fork, 45.0 mm shock stroke (Sport, Comp, Expert, Pro, S-Works, S-Works LTD)

Riding style	Fork SAG	Shock SAG
XC / touring	17 % = 20 mm	24 % = 10.8 mm on the shock shaft
Trail	20 % = 24 mm	28 % = 12.6 mm on the shock shaft
Enduro / rough	22 % = 26 mm	30 % = 13.5 mm on the shock shaft
Bike park	20 % = 24 mm	27 % = 12.2 mm on the shock shaft

110 mm fork, 45.0 mm shock stroke (S-Works Ultralight LTD)

Riding style	Fork SAG	Shock SAG
XC / touring	17 % = 19 mm	24 % = 10.8 mm on the shock shaft
Trail	20 % = 22 mm	28 % = 12.6 mm on the shock shaft
Enduro / rough	22 % = 24 mm	30 % = 13.5 mm on the shock shaft
Bike park	20 % = 22 mm	27 % = 12.2 mm on the shock shaft

How to measure SAG is explained in our guide SAG setup.

Tyre pressure starting values

For 2.35″ 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: Air Trak 2.35; Fast Trak / Air Trak 2.35.

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.

Note: all information without guarantee. Specs can differ by model year, frame size and market – the type plate, the owner’s manual and Specialized’s information are authoritative. Never exceed the maximum pressures of fork, shock, tyres and rims.
