  • Patent number: 9770944
    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.

According to the invention, these lateral portions are capable of having a portion of their axial width cut off by the detachment of two respective peripheral sections (15a and 16a) of these lateral portions, so that this ribbon extends from one of the said edges to the other following this detachment.

  • Patent number: 7874625
    Abstract: A bicycle wheel assembly having a number of spokes that extends between a hub and a rim. The wheel assembly includes a drive side that faces a chain and a non-drive side that is laterally spaced from the drive side. The spokes that extend between the hub and the rim on the drive side of the wheel assembly are oriented in a series of radial spokes and one-cross spoke pairs. Preferably, the drive side spokes are oriented in a repeating pattern. The non-drive side spokes are oriented in a repeating pattern wherein each spoke crosses more than one other non-drive side spoke. A wheel having such a spoke lacing pattern is lightweight and robust.

  • Publication number: 20100078987
    Abstract: A spoked wheel is described that uses flexible spokes having a termination on each end that couple with a rim using nipples. The flexible spokes are supported mid-span by a hub flange cradle that transfers torque from the hub to the rim via two sub-spokes. The hub flange cradle determines whether a sub-spoke is tangential or radial. A plurality of spokes may be used on each side of the wheel. Spoke tensegrity couples the hub to the rim.
