Wilbers Fork Spring - Zero friction - Progressive Wilbers We also fine‑tune chassis geometry

We also fine‑tune chassis geometry by increasing negative travel slightly while maintaining seat height for a neutral

divey under hard braking

and YSS’s advanced fork emulator valves (PD Valves)

Our softer spring with matched rebound/compression damping markedly improves comfort and control

Wilbers Fork Spring - Zero friction - Progressive Wilbers We also fine‑tune chassis geometryWilbers progressive fork springs ZERO Friction finishing Our vibratory finishing process (trough vibrator with tailored media) micro polishes the spring surface. The resulting fine, shiny finish reduces surface roughness and friction hence ZERO Friction. Pair with our specially formulated Wilbers fork oil and the specified air chamber for your vehicle to maximize performance. Product may differ from the picture. Recommended viscosity and air chamber:
