What Is the JBI Pro Perch?
  • The JBI Pro Perch is a high performance replacement spring perch for KYB, Showa, & WP Twin Chamber forks.
How Does the JBI Pro Perch Work?
  • Unlike stock spring perches that feature "fixed" holes for oil to simply flow through, the JBI Pro Perch is pressure sensitive meaning the port area (hole size) for fork oil to flow through is based on pressure. (Small pressure = small port area / High pressure = large port area).  This "active" style of damping at the spring perch results in a fork that is plush on small bumps yet firm enough to soak up those hard hits & landings without being harsh.
