Shock Absorber Type 640 Road Preload Adjuster:Mechanical (X-PA) (+$460) the pressurized (3 bar nitrogen)

the pressurized (3 bar nitrogen) closed cartridge maintains bubble-free damping for consistent feel at extreme loads and temperatures

The only difference is that it omits the compression reservoir and therefore the ability to adjust high- and low-speed compression

ultra-low-friction ZERO Friction fork springs

Send in your fork for rework or lowering

This prevents oil thinning and cavitation (foaming) during hard

This is achieved by replacing the stock linear fork springs with progressive ones, allowing for a smoother initial reaction and greater reserve in the second spring rate. The original shock absorber has relatively high rebound damping. In our setup, the spring rate has been slightly increased and both rebound and compression damping optimized. Additionally, the suspension
