Abstract: A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

Abstract: Embodiments of golf club heads with apertures and methods to manufacture golf club heads are generally described herein. In some embodiments, a golf club head comprises a face portion, a back portion generally opposite the face portion, a heel portion extending between the face portion and the back portion, a toe portion opposite the heel portion and extending between the face portion and the back portion, and a crown portion extending between the face portion, the back portion, the heel portion, and the toe portion, the crown portion comprising a plurality of crown aperture. The crown portion comprises a first region and a second region, wherein the first region is nearer to the face portion than the second region, the first region and the second region are separated by a bell-shaped curve. The bell-shaped curve is located a distance D1 from the face portion and the second region comprises a recess portion. The plurality of crown apertures is defined within the recessed portion. In some embodiments, the golf club head comprises both metal and fiber-based composite portions. In other embodiments, the golf club head comprises a plurality of sole apertures. Other embodiments may be described and claimed.

Abstract: Improved skateboards and methods of obtaining or providing skateboards with improved trucks. Trucks have two axles or axes, two primary wheels, and two secondary wheels, and skateboards have eight wheels, four in front and four at the rear portion of the skateboard. The four primary wheels support most or all of the weight of the skateboard when the skateboard is on a flat surface, and the two secondary wheels support the weight of one portion of the skateboard (e.g., front or rear) when the primary wheels cross a crack (e.g., a sidewalk contraction joint). In various embodiments, the secondary wheels are located outboard of the primary wheels. Further, in a number of embodiments, the axis of rotation or axle of the primary wheels remains parallel to that of the secondary wheels, whether the skateboard is going straight or turning.
