Dust and other environmental factors cause fork stanchions to become less responsive which leads to loss of travel and slow response it feels stiff over even very small bumps. Finish Line's Max Suspension Spray is designed to give a fork new life between overhauls. Formulated from polysiloxane and fluoropolymers the Max Suspension Spray reduces friction while protecting seals, o rings, and other rubber parts. It works with the surface of any stanchion, even those that have a coated surface. The Finish Line Max Suspension Spray comes in a 6oz aerosol can.
