"1. Internal Floating Piston (IFP)Air Pressure Settings - The shockdepends on air pressure
tofunction properly. Use of theshock with improper IFP airpressure will cause damage &failure of the
shock that is notcovered by the warranty. The IFPair pressure settings control theposition sensitive
damping feature of the shock. IFP air pressure adjustments vary thestarting compression force that
affects the pedaling platform & high-speed blow-off.The IFP air pressure range is 50-125psi. Never
use a pressure outside this pressurerange. You can refer to the online Quick Start guide at:
www.progressivesuspension.com/literature.html for accurate pressure ranges matched to your bike
model and body weight.The IFP air pressure also affects sag, so you should set the IFP air pressure
beforesetting the main spring pressure. The IFP pressure settings will vary according to
riderweight, main spring pressure, your bike’s leverage ratio & your personal preferences.Lower
pressures will provide a softer ride & lower blow-off threshold for sharp, high-speed bumps. Higher
pressures will provide a firmer ride control, firmer pedaling &higher blow-off threshold for sharp,
high-speed bumps.
3. Main Air Spring PressureAdjustments – Air Springadjustments are made byinflating or deflating the
main airspring chamber. Since your IFP air pressure adjustment (outlined above) also affectsyour
starting spring force, you should always adjust your IFP pressure before adjustingthe main air
spring pressure. You can refer to the online Quick Start guide
at:www.progressivesuspension.com/literature.html for accurate main air spring pressure23
4. Rebound Damping Adjustment - The rebound damping controls the return rate ofthe shock & rear
wheel after it has compressed to absorb the bump. The reboundadjustment will vary for different
air spring pressures, rider weights, leverage ratios,type of riding and individual rider
preferences. As a general rule, adjustments thatare too fast (counterclockwise adjustment) will
produce a springy ride with excessivekick-up of the rear end during aggressive riding or racing.
Adjustments that are tooslow (clockwise adjustment) will cause packing of the rear wheel that is
identified bya low ride height & stiff ride feeling when the rear wheel can’t return fast enough
toabsorb the next bump. An average starting adjustment will achieve a return movementof the shock
somewhere between a “snap-back” and”“sluggish” motion. You canrefer to the quick start guide for
an average starting setting for your bike model,spring rate and rider weight. The rebound
adjuster is a red knob found on the eyeletcap of the main air chamber. All models are fitted with
a knurled knob for easy no-tool adjustment.When reaching the minimum &maximum stops of the
adjusterrange, do not apply excessiveforce to continue turning theadjuster, or damage to
theadjuster will occur that is notcovered by the warranty."
