Damping is mainly needed to quickly stop oscillation caused by bumps on the road so that the chassis is immediately ready for the next bump.
Furthermore: The dynamic forces change depending on where the center of gravity is, which is determined by the size and weight of the rider and luggage.
A further influence: If a rider works hard and moves his/her upper body unevenly, the suspension can be subjected to additional forces.
As a recumbent rider, you benefit from a further physical advantage over the conventional upright cyclists: In the laid-back position, you pedal forward and thus place few downward forces on the suspension.
On your HP Velotechnik recumbent, unwanted effects are suppressed during the decompression cycle by an oil stream inside a refined hydraulic damper. If you select the lightweight air shock from RockShox, you can alter the rebound damping settings with an adjusting wheel and optimize your chassis to your specific ride situation.
A good setting for maximum comfort is achieved when the rear wheel decompresses completely after a shock and then oscillates only once. Your vehicle will react quickly to the slightest bumps.
