Abstract
Abstract A skate truck including a wheel assembly baseplate rigidly secured to the underside of a skateboard and with a curved recess depending therefrom, two beams integrally molded in a letter "V" are provided. One end of the beams is securely anchored to the baseplate and the other two ends are mounted in an obtuse angle to an axle hub. A peg extends upwardly from one side of the axle hub and is connected to a buffer which contacts or is adjacent to the curved recess to absorb wobble or vibration and also to maintain meneuverability and stability.
