Abstract
An aerodynamic bicycle rim comprising: a circumferential outer portion comprising a circumferential outer surface, the circumferential outer portion adapted to seat a bicycle tire; 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 maximum rim body width that is greater than a maximum width of the bicycle tire. The aerodynamic bicycle rim is operable to seat the bicycle tire so that the aerodynamic bicycle rim and the bicycle tire form an asymmetrical cross-sectional shape.
Claims22
An aerodynamic bicycle rim comprising:
- a circumferential outer portion comprising a circumferential outer surface and forming a radially outermost 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 maximum rim body width at a widest part of the rim body, a second width at a centerline of the rim body, and a rim body depth, each sidewall and corresponding transition forming a continuous outer surface around the rim body from the radially outermost edge to the nose, wherein the continuous outer surface curves laterally inward at the corresponding transition and wherein the continuous outer surface has a curved shape from the widest part of the rim body to the nose;
- and
- wherein the widest part of the rim body is spaced away from the centerline of the rim body, and wherein the circumferential outer portion is adapted to seat a bicycle tire that is narrower than the maximum rim body width and narrower than the rim body is deep to form an asymmetrical cross-sectional shape having a centerline that is spaced from the widest part of the rim body.
An aerodynamic bicycle rim, the aerodynamic bicycle rim comprising:
- a nose;
- and
- a set of sidewalls, each sidewall extending radially outward from the nose to form a rim body having a radially outermost edge distal the nose, the rim body having a maximum rim body width at a widest part of the rim body that is spaced radially inward of the radially outermost edge of the rim body and radially outward from a centerline of the rim body, each sidewall transitioning to the radially outermost edge of the rim body at a corresponding radiused transition that curves laterally inward, wherein the rim body increases in width from the radially outermost edge of the rim body to the widest part of the rim body and decreases in width from the widest part of the rim body to the nose;
- and
- wherein, the aerodynamic bicycle rim is operable to seat a bicycle tire that is narrower than the maximum rim body width to 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 a sidewall of the set of sidewalls, the tangent line having a tangent angle of less than 17 degrees.
An aerodynamic bicycle rim, the aerodynamic bicycle rim comprising:
- a nose;
- and
- a set of sidewalls, each sidewall extending radially outward from the nose to form a rim body having a radially outermost edge distal the nose, the rim body having a maximum rim body width at a widest part of the rim body that is spaced radially inward of the radially outermost edge of the rim body and radially outward from a centerline of the rim body, wherein the rim body increases in width from the radially outermost edge of the rim body to the widest part of the rim body and decreases in width from the widest part of the rim body to the nose, each sidewall transitioning to the radially outermost edge of the rim body at a corresponding radiused transition that curves laterally inward;
- and
- wherein, the aerodynamic bicycle rim is adapted to seat a bicycle tire that is narrower than the maximum rim body width and narrower than the rim body is deep to 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.
