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.

A saddle-riding-vehicle front part structure includes: a suspension that is arranged at a rearward position of a steering shaft and at an upward position of a power source; a support shaft that supports the suspension and that is provided between a pair of right and left arms; and a cover that is provided between the steering shaft and the suspension and that covers a space between the pair of right and left arms, wherein the cover includes a pair of right and left first cover parts that correspond to the pair of right and left arms and a second cover part that corresponds to the suspension, and the pair of right and left first cover parts and the second cover part are displaceable independently from each other.

A bicycle frame includes an antenna and is formed with the antenna as an integrated part of the frame structure, and the antenna constituting part of the outside of the bicycle frame. In a method of equipping a bicycle frame made from carbon with an antenna, the antenna is interwoven with the carbon structure of the bicycle frame as part of the production of the bicycle frame.
