Motorcycle Fork Rebound Piston Mounting Posts
Rebound Base Tower / Post
Motorbike front forks are more than the two outer tubes — a separate internal cartridge does the work. A cartridge rod slides inside that cartridge, and at the top of a cartridge rod assembly sits the piston holder tower or rebound base post which secures piston parts and valving stacks.
Function of Rebound Base Towers
- Holds the rebound piston parts and valving shim stacks on the threaded upper post portion using a mechanical locknut.
- Transmits clicker adjustments from the axle feet to the valving stack via the hollow cartridge shaft and inner pushrod.
- Enables precise rebound damping by changing oil flow and damper resistance.
- Provides a serviceable mounting point for piston components during revalving or rebuilds.
