regular intervals. |
|
|
Turn Brain Fade knob |
|
|
(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.
