Abstract
A bicycle rim is configured to reduce drag as well as enhance steering stability, such as in gusty and/or high cross wind conditions. The rim includes a leading edge where the rim interfaces with a tire, and a sidewall extends from the leading edge. The rim includes a spoke face where one or more spokes extend from the bicycle rim. A reflexed blend portion is disposed between the sidewall and the spoke face. The reflexed blend portion allows the sidewall to have increased camber which lowers pressure drag. At the same time, the reflexed blend portion allows the spoke face to have a larger radius so as to provide greater steering stability, such as in gusty and/or high cross wind conditions.
