Rear Shock Setup: | Because it is highly likely the original rear shocks on older models are repaired/replaced/ upgraded throughout the lifetime of the frame, we offer some very basic tuning guidelines, and recommend using the original rear shock manufacturers manual for more detailed set-up for the specific rear shock you have. Contact the rear shock manufacturer for info if you do not have it.The key component for set-up with any rear shock here is sag. Once you have that set-up correctly, the rest of the shock settings are fine tuning adjustments (Rebound and Compres- sion damping, etc.) set to rider preference.Recommended sag is for the XS and Small frame sizes is 8-12mm Recommended sag is for the Medium and Large frame sizes is 10-15mm This equates to approximately 20-30% of the total rear wheel travel.Less sag = a firmer suspension feel.For Air rear shocks, set the air pressure to match the recommended sag.Typically for this Medium and Large size frames with Fox rear shocks the PSI is equal to rider weight (150lb rider = 150psi). For the XS and Small sizes the typical pressure is weight + 25psi (150lb rider = 175psi) but again this varies by rear shock model. Sag is the key. |
