A suspension fork includes a steerer tube, a crown attached to the steerer tube, and a pair of fork legs extending from the crown. Each fork leg has a hollow stanchion telescopically inserted into a hollow lower. A piston having a piston head separates the stanchion into a positive and a negative air spring chamber. A base is disposed inside the stanchion and is secured to the stanchion such that the base is arranged between a closed end of the lower and the piston head. A floating piston is slidably disposed inside the negative air spring chamber and divides the negative air spring chamber into a first chamber and a second chamber. The floating piston moves towards the piston head in response to a pressure created inside the lower to facilitate a passage of air from the lower to the second chamber through a communication port defined by the base.
