From the Fox Shox manual....

Leverage ratio = 1.8 (stock, not DG or other after-market swing arm)
Bike weight = 210-230lbs
Rider weight = 220lbs with gear
(Upper) Low pressure = 91 psi
(Lower) High pressure = 146psi

The greatest thing about Fox Shox is you can so easily make adjustments to these settings. If you ever want these re-built or re-furbished, ask me about Brian Rivers in Florida.

Michael, can pass on the contact info for Brian in Florida, I have a set of Fox Shocks that are in need of a rebuild and I live in the sunshine state. Thanks, Dave
