Reigers B40 Factory version of the trial dampers now come with a larger 40mm main piston diameter giving greater damping control and improved reliability. They still have the same 4 way adjustable damping control, and the spring pre-load adjustment.

The damper has an adjustable spring preload, a rebound adjustment to balance control and stability, high speed compression adjustment to control the large hits and low speed compression adjustment for the slower movements.

The B40 Factory version was developed together with Adam Raga, multiple world champion, in this partnership they developed the hydrostop feature.

The hydrostop adjuster makes the compression damping very progressive at the end of the damper travel, which prevents bottoming. This is also adjustable.
