All our trial dampers have adjustable spring preload and a rebound adjustment to balance control and stability. We have shock absorbers with compression and (high/low speed) compression adjustments .
Together with Adam Raga, multiple world champion, we have developed the hydrostop and bottom rebound.
The hydrostop makes the compression damping very progressive at the end of the damper travel, which prevents bottoming. The bottom rebound keeps the damper compressed for an adjustable time so that you keep traction. This feature especially helps when driving vertically.
