EPIC / ERA REAR SHOCK SETUP
1. Set sag:
• See the attached air chart for starting pressure. Use a high-pressure shock pump to add air.
• Turn the Brain Fade knob (3) counter-clockwise to allow the shock to sag more easily.
• Push the o-ring up to the seal, sit on/dismount the bike gently, measure the distance between the shock seal and the o-ring (sag).
• Adjust air pressure until the desired sag is reached (verify following the steps on page 6 or the measurements below the air chart).
Air pressures may vary depending on rider style and/or terrain.

2. Adjust rebound:
The red knob (2) controls the rebound damping, the rate which the shock returns after the shock
has been compressed.
• Turn the knob clockwise for slower rebound (slower speed, bigger hits).
• Turn the knob counter-clockwise for faster rebound (higher speeds, small bumps, more traction.
Eye-to-eye length: 307.3mm
Shock stroke: 47.6mm
Recommended sag: 20-25%
(9.5-12mm)
Firm (race sag) setting: 15-20%
(7.5-9.5mm)
3. Tune Brain Fade inertia valve:
Brain Fade is an inertia valve system offering a range of pedal platform efficiency. The blue knob
(3) controls the Race Tune inertia valve damping.
• Turn the knob clockwise for a firmer, more efficient ride. Full clockwise is hardtail firm in
smooth terrain.
• Turn the knob counter-clockwise for a softer, more supple Trail Tune setting.
