Abstract: A bicycle includes a front wheel and a rear wheel and a frameset supported on the front wheel and the rear wheel. The frameset includes a main frame and a front fork rotationally coupled to the main frame. The main frame includes a top tube, a head tube rotationally supporting the front fork, a down tube coupling the head tube to a bottom bracket, a seat tube extending downward from the top tube and including a lower end spaced from the bottom bracket, a seatstay extending rearward from the lower end of the seat tube, and a strut member extending forward from the lower end of the seat tube and connecting the seat tube to the down tube.

Abstract: A bicycle includes a frame having cross sectional profiles. The profiles are designed according to certain criteria to enhance bicycle performance. The profiles for multiple frame members may each fall within a range for each of aspect ratio, circumference, drag coefficient, first moment of inertia and/or second moment of inertia.

Abstract: A bicycle includes a frame, a front and rear wheel and a crank assembly. The frame includes chainstays and a bottom bracket having a center and which rotationally receives the crank assembly. The crank assembly includes a chain ring having a radius between the bottom bracket center and a circumferential edge. The chainstays are connected to the bottom bracket at a first end and rotationally receive the rear wheel at a second end. The chainstay defines a cutout sized to receive a portion of a circumferential edge of the chain ring.

Abstract: A bicycle wheel is disclosed having a spoke, a nipple coupled to the spoke, and a rim coupled to the nipple and having an annular panel with inner and outer surfaces and an access hole. A plug is positioned over the access hole and includes a cap that is larger than the access hole, a leg extending from the cap and through the access hole, and a barb protruding radially from the leg to at least partially engage the inner surface of the annular panel. The plug can further include a resilient member compressed between the cap and the outer surface of the annular panel. On some rims, the annular panel has a non-planar contour. For these rims, the resilient member and/or the cap can be shaped to match the non-planar contour of the annular panel.
