    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.

    Abstract: A golf club head including a strikeplate including a strikeplate stiffness, a strikeface, and backface opposite the strikeface. The head also includes a modulation mechanism at the backface, a plurality of frequency modulators, and a plurality of anti-stiffening features interspersed between the plurality of frequency modulators. The plurality of frequency modulators reduces an oscillation frequency of the strikeplate upon impact with a golf ball. The plurality of anti-stiffening features permit flexing of the strikeplate between the plurality of frequency modulators.

    Abstract: Improved trucks for skateboards, skateboards having improved trucks, 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 primary wheels are located outboard of the secondary wheels, are wider, or both. 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.
