10. BRAIN FORK SETUP
Your Epic WC is equipped with a RockShox fork featuring Specialized Brain
technology. Please read all of the information in this section as well as
RockShox’s Suspension Fork User Manual in its entirety for proper setup
and service before riding.
10.1. General information about Brain technology
The Brain is an inertia-valve platform that supports the fork and
distinguishes between terrain or rider-weight-induced events. This
provides two distinct compression damping rates: one to react to the
terrain and the other to support the rider.
The Brain Fade is the fluid bypass circuit that allows the rider to modulate
the firmness of the inertia valve and allows the rider to select between a
firmer or softer platform.
This particular Brain fork is equipped with Position Sensitive Brain
technology (PSB). With PSB, the Brain platform doesn't engage until
15-20% into the fork's travel allowing for proper sag, increased traction,
and small bump compliance. Once your fork travels 15-20%, the Brain
platform engages. The position the Brain engages is pre-set from the
factory but can be internally adjusted by an Authorized Specialized
suspension technician.
Below is the pressure chart for this fork model. It’s also located on the
back of one of the fork legs.
