As we have been playing around with my gal's components on her Bullit and XC Bike's we have come to the following conclusion. Air may not be the way to go for somebody under 120 lbs. When air pressure is lowered enough to become plush and small bump compliant the Fork/Shock becomes sluggish and loses the ability to rebound. This is the case with Nixon Platinum, Swinger 3 way, Swinger 4 way, Fox RP3. She has gone back to coil over on all the shocks and will probably go to a Pike Coil and Boxxer Team with light springs on the front. The only fork we have used that seemed to be able to set up for her weight is a 05 Fox Talus. The worst is the Fox RP3. I also found if I droop the SPV pressure below 50 psi on the Nixon Plat it creates a knocking sound internally.
