Aerodynamic bicycle rim and wheel

An aerodynamic bicycle wheel comprising:

• a bicycle tire;
• a bicycle rim to which the bicycle tire is mounted, the bicycle rim comprising:
• a circumferential outer portion comprising a circumferential outer surface, the circumferential outer portion adapted to seat bicycle tire;
• a nose;
• and
• a set of sidewalls, each sidewall extending radially from the nose of the bicycle rim to a corresponding transition to the circumferential outer surface to form a rim body having a maximum rim body width at a widest part of the rim body that is wider than a maximum width of the bicycle tire, a second width at a centerline of the rim body that is wider than the maximum width of the bicycle tire and a rim body depth that is greater than the maximum width of the bicycle tire, each sidewall and corresponding transition forming a continuous outer surface around the rim body from the circumferential outer surface to the nose, wherein each sidewall has a curved shape from the widest part of the rim body to the nose;
• wherein the bicycle rim seats the bicycle tire so that the bicycle rim and the bicycle tire form an asymmetrical cross-sectional shape in which the widest part of the rim body is spaced from a centerline of the asymmetrical cross-sectional shape and there is a tangent line tangent to bicycle tire and tangent to a sidewall of the set of sidewalls, the tangent line having a tangent angle of less than 17 degrees.

An aerodynamic bicycle rim comprising:

• a circumferential outer portion comprising a circumferential outer surface and forming a radially outer edge;
• a nose;
• and
• a set of sidewalls, each sidewall extending radially from the nose of the aerodynamic bicycle rim to a corresponding transition to the circumferential outer surface to form a rim body having a depth that is greater than thirty millimeters, each sidewall and corresponding transition forming a continuous outer surface around the rim body from the radially outer edge to the nose and that has a curved shape from a widest part of the rim body to the nose;
• wherein the aerodynamic bicycle rim is operable to seat a bicycle tire that is narrower than the widest part of the rim body and narrower than a width of the rim body at a centerline of the rim body so that the aerodynamic bicycle rim and the bicycle tire form an asymmetrical cross-sectional shape in which the widest part of the rim body is spaced from a centerline of the asymmetrical cross-sectional shape and there is a tangent line tangent to the bicycle tire and tangent to a sidewall of the set of sidewalls radially outward from the widest part of the rim body, the tangent line having a tangent angle of less than 17 degrees.
