    Clearance check between shock absorber and bike frame After purchasing the Nebbia air shock, it’s important to check the clearance between the shock absorber and the frame or linkage for the entirety of its travel. The air shock is provided with a standard pressure of 150 psi, always use the Formula pump and perform checks as explained by Formula to properly check the pressure to avoid improper pressure checks.
  • Page 6: Sag Setting

    SAG Setting Setting up the SAG is useful for understanding the shock absorber’s behaviour depending on the rider’s weight and the bike discipline. 1. The SAG INDICATOR is a quick way to recognise the SAG depending on the bike usage: the SAG increases when the OR for SAG is farther from the seals.
  • Page 7: Rebound Adjuster

    To increase the rebound force, rotate the adjuster clockwise. Viceversa, to reduce it. During the initial set-up, Formula suggests closing the adjuster by fully rotating it clockwise and then rotating it anti- clockwise by 12 clicks.
  • Page 8: Compression Adjuster (Cts)

    Rotate the knob clockwise to increase the shock absorber’s force during compression; this allows for better support in the rear end of the bike. Rotating the knob anti-clockwise, instead, reduces the support on the rear end. During the initial set-up, Formula suggests fully rotating the adjuster clockwise and then rotating it anti-clockwise by 10 clicks.
  • Page 9: Lock-Out Lever

    Lock-Out Lever The Lock-out lever gives more support during the compression phase of the shock absorber to improve efficiency during riding. This is useful especially when ascending with an MTB. You can choose the preferred setting with the purple lever (11). The Lock-Out has 3 clicks, each one corresponds to a specific setting: open, platform and closed.
  • Page 10: Change Shock Absorber Stroke

    Change shock absorber stroke Required Tools: Bench Vise, Formula grease. Procedure: 1. Place the shock absorber in a bench vise with plastic jaws to prevent damage. Remove the SAG indicator o-ring (42); Fully depressurize the reservoir from its valve (1) ensuring the pressure is zero. Disassembling a pressurized shock absorber can cause severe injuries.
  • Page 11 5. Move the bumper (11) on the spacer, then apply grease to the air sleeve (2) where highlighted in red and insert it onto the shock absorber, tightening it by hand; 6. Pressurize the shock absorber to 150 psi and screw on the air valve cap (1). During the pressurization of the shock absorber, it will extend until it reaches the correct centre distance.
  • Page 12: Cts Replacement

    CTS Replacement Required Tools: Bench Vise, Formula grease, Torx T10, 13 mm Socket Wrench. Procedure: 1. Keep the CTS facing upwards to avoid oil leaks during the procedure. Remove the CTS screw (31) with a Torx T10 and remove the adjuster (61). Unscrew the CTS (60) from the body with a 13 mm socket wrench;...

    Troubleshooting Problem Root Cause Solution The shock absorber is too fast during Rotate clockwise the rebound extension, or after a jump the rear end Rebound setting is too open regulator by 1/2 clicks at a time and try of the bike throws me forward again The shock absorber is too slow during Rotate anti clockwise the rebound...
  • Page 14 Wear safety glasses. Disassemble the shock from the frame, completely remove pressure from the air sleeve, tighten the body shock in a bench vise. Insert a rag in the eyelet and manually unscrew the air sleeve with grippy gloves. Ensure During the complete extension (TOP the air seals are properly assembled OUT) the shock absorber makes a...
