REAR SHOCK SETUP

NOTE: This air chart is designed as a

recommended starting point only. Please

refer to your shock owner’s manual for

additonal setup information.

Rear Air Shock Setup

AFR Brain Fade

Sag Setting: Set the sag at 22 to 28% of

shock stroke.

10-12mm for 26” FSR

8.5-11mm for 29er FSR.

See attached chart for starting air pressure.

Note - the chart is only a starting point,

actual sag needs to the checked and

adjusted on the bike, while riding, and at

regular intervals.

Turn Brain Fade knob counter-clockwise

(1 to 1.5 turns from full firm) to allow

shock to sag more easily. After setting the

pressure, push the rubber ring up to the

seal, sit on the bike gently, dismount, and measure sag.

AFR Brain Fade Compression setting: After the sag is set, adjust the Brain Fade to full

firm or rider preference.

AFR Brain Fade ride tips: Stumpjumper Brain Fade controls the Trail Tune inertia valve

damping. The blue knob adjusts Trail Tune damping from firm (clockwise) to soft

(counterclockwise) and does NOT completely lock out the shock (ie. Epic).

Backing off from full firm can help with tracking in loose terrain conditions while riding

off camber sections or climbing. The soft setting can also help during lengthy downhill

or rugged conditions where the rider may want the suspension active at all times.

Rebound setting: Set rebound damping adjuster to rider preference. A good starting

point is 9 clicks out from full firm. Typically a slower rebound for slow speed, bigger

hits to eliminate kickback, or faster rebound for higher speeds and smaller hits, so the

suspension does not pack up and has time to rebound between bumps.
