It looks like a piggyback on the shock, but the "Secus" from Canadian spring specialists "Vorsprung" can do something else: the tuning part is not connected to the damping circuit of the fork, but to the air chamber. This results in a spring curve that triggers a better response to small and medium impacts, i.e. is based on a steel spring curve. At the same time, the air suspension fork can be tuned with tokens to adjust the end progression.
