Aerodynamic bicycle rim and wheel

摘要

Embodiments described herein provide aerodynamic bicycle rims and wheels. Embodiments can include a bicycle rim that is wider than the width of the tire proximate to the outer edge of the rim and is shaped so that there is a tangent line tangent to the rim and the tire. The tangent line can be tangent to the rim on the sidewall or elsewhere on the rim. The widest part of the rim can be radially inward from the outer edge of the rim or elsewhere on the rim and the tangent line can be tangent at the widest part of the rim or elsewhere on the rim.

1. An aerodynamic bicycle rim comprising:
a circumferential tire mounting surface on a radially outer side of the bicycle rim forming a tire bed to seat a tire; and a set of sidewalls, each sidewall extending radially from a nose of the bicycle rim to a corresponding transition to the circumferential tire mounting surface to form a bicycle rim body having a maximum rim body width at a portion of the rim body that overlaps the tire bed, the maximum rim body width greater than a maximum width of the tire; wherein, the bicycle rim is operable to seat the tire so that the cross-sectional shape of the tire and rim body is asymmetrical about the widest portion of the cross-sectional shape and there is a tangent line tangent to the tire and tangent to a sidewall of the bicycle rim radially inward from a radially outermost edge of the rim body having a tangent angle of 8-17 degrees, wherein the rim is configured such that a wheel formed by the rim and tire has a stall angle of 10-19.5 degrees when the tire is seated.
