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 Compression damping, etc.) set to rider preference.Recommended sag is 8-13mm at the shock shaft - This equates to approximately 15-25% 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 model the PSI is approx 25% less than rider weight, but again this varies by rear shock.For Coil rear shocks here is a rough spring size to weight guideline for average coil shocks.
 This can vary based on rear shock model and manufacturer.100-130lbs - 225-250#140-160lbs - 300#170-200lbs - 350#210-240lbs - 400-450#
