Wilbers 641 Competition Shock Absorber with Separate Nitrogen Canister

In the Rieju Power Parts catalog, we include the Wilbers 641 rear shock absorber. It is the top-of-the-line model.

It features a 46 mm internal piston, specifically valved for each customer, with the optimal spring stiffness for the rider’s weight. The shock absorber is fully customized.

It includes a radial piston, high-quality shims, an extra-hard rod, a separate nitrogen canister with external high-speed (automatic) and low-speed compression adjustments, as well as rebound speed adjustment and preload by notched crown and counter-crown (adjustment key included as standard).

The spring color can be chosen in either black or navy blue.

After the purchase, the customer will be contacted to define the shock absorber according to their characteristics.
