This invention relates to polygonal frame structures made from anisotropic materials, and methods for their construction. The polygonal frame structures include at least one frame member that is constructed as a torsion box. The torsion box is constructed with layers of anisotropic materials, resulting in a lightweight, torsionally stiff polygonal frame. Natural and/or man-made anisotropic materials may be used. Wood may be used as a natural anisotropic material. The invention is applicable to bicycles and other vehicles, as well as other products, where frame structures having light weight and torsional stiffness are advantageous.

A bicycle has a front fork, within which the front wheel is mounted, attached to the head tube. Extending downwardly from each end of a lateral member are downwardly projecting forks, each comprising a primary portion, the respective primary portions extending downwardly and substantially parallel to each other. The longitudinal axes of both the main portion and a rider's lower leg are aligned. By aligning the wakes created by the forks and the lower leg a reduction in overall system drag is provided. Additionally or alternatively, the rear wheel may be provided between downwardly projecting stays, each comprising a primary portion, the respective primary portions extending downwardly and substantially parallel to each other. By aligning the downwardly projecting stays with the lower leg beneficial drag reduction is achieved.

The present disclosure relates to a bicycle frame and associated bicycle components, and to reducing the aerodynamic drag of these. In one aspect, there is provided an elongate structural member of a bicycle frame, the member comprising a lengthwise extending leading edge, the leading edge comprising at least a pair of forwardly extending protrusions spaced apart lengthwise therealong. In one form, the protrusions comprise tubercles, a series of which are spaced apart lengthwise along the leading edge, and which further extend to at least one side of the leading edge so as to transition into a chordwise extending rib.
