Riding Airbag Cartridge Replacement Guide

Step 1 – Removing the used cartridge

After the airbag deploys, the ball is ejected, and the spring becomes visible.
Unscrew the used CO₂ cartridge, then remove it completely.

Step 2 – Loosening the system

Using the supplied Allen key (5 mm), loosen the cap.
Do not unscrew it completely, but only enough to reposition the piston.

Step 3 – Repositioning the piston

Reposition the piston using the Allen key or your finger.
Ensure that the piston's notch is perfectly aligned with the hole intended for the ball.

Step 4 – Replacing the ball

Replace the ball in its housing.
Make sure the ring around the ball is positioned flat.
Start screwing the cap back on by hand while firmly holding the ball.

Step 5 – Tightening the mechanism

Finish tightening the cap using the Allen key.
The cap must be in contact with the cylinder.
Do not overtighten to avoid damaging the system.

Step 6 – Installing the new cartridge

Screw in a new CO₂ cartridge suitable for your airbag size.
Tighten completely without forcing, ensuring the cartridge is correctly aligned.

Recommended cartridges

  • 50 cc for sizes 3XS to XS

  • 60 cc for sizes S to XL

Points of attention

  • Always use a new cartridge after deployment
