When setting up air shocks we recommend starting by replicating the sag point you have found to feel best with the stock link. General rule of thumb to get you close is multiply your air pressure with the stock link by 1.10 (10% increase). You always want to be at near 30% sag because if your sag is too much higher than that, the anti-squat will be lower and the bike won’t pedal as well. At 30% sag use damping and volume spacers to tune the shock’s feel throughout its stroke. Keep in mind that damping is not position sensitive, it is shock speed sensitive. If you like how the damping feels during a certain portion of your bike’s travel play with the volume spacers and don’t tweak damping yet.
Due to the weight of this bike we don’t recommend running a coil shock because recommended spring rates are quite high. A majority of riders will find that an air shock is more versatile and can accommodate a wider range of rider weights.
