1. A suspension system for a wheel assembly of a vehicle, the suspension system comprising:
a. a telescopic damper configured to mediate between an unsprung portion and a sprung portion of the wheel assembly, the telescopic damper comprising a rebound striker and a piston rod assembly including a rebound stop; and
b. an internal rebound cylinder disposed within the telescopic damper, the internal rebound cylinder encompassing the rebound stop, an active chamber of the internal rebound cylinder being arranged in fluid communication with a hydraulic system controllable to regulate a pressure in the active chamber so as to change a position of the internal rebound cylinder relative to the rebound striker,
wherein the suspension system is effective, in a first operating mode, to regulate a wheel rate of the wheel assembly, and the hydraulic system is controllable to change a wheel-travel value at which the wheel rate of the wheel assembly changes in the first mode of vehicle operation.
