A truck guard assembly for a truck of a skateboard is provided. The assembly can include a guard body having an outer grinding wear surface configured to contact a riding surface during use, a central cavity for receiving a portion of the truck therein, and a coupling latch hingedly coupled to the guard body. The coupling latch can be rotatable between a closed position, enclosing the central cavity, and an open position, for installation or removal of the assembly with respect to the truck without removing the truck from the skateboard. The elongate guard body can further include a relief cut for clearance from the truck when installed, and a flint channel extending at least partially along the outer grinding wear surface and configured to receive a flint rod therein. The flint channel can have a necked down portion to retain the flint rod within the flint channel during use.

A seated wakeboard suspension system comprising a support frame (2) for a seat (1) mounted on a fixed frame (9) attached to the board (13) by means of a two-link (4, 5) linkage and a movable frame (3) forming a deformable quadrilateral (14). The links (4, 5) are articulated at their upper ends to the movable frame (3) and at their lower ends to the fixed frame (9). The deformation of the quadrilateral (14) generates, without unbalancing the user, a significant vertical displacement at their center of gravity and almost no horizontal displacement. A shock-absorbing element (8) is articulated on the rear link (5) and on an intermediate point of a three-point link (7), itself articulated at its base to the fixed frame (9). A two-point link (6) connects the rear link (5) to the top of the three-point link (7) to make the suspension progressive. Figure to be published with the abbreviation: [Fig 1].
