Abstract
A spoked bicycle wheel is presented where the masses of a set of spoke connections for connection of a hub and a rim as a whole are imbalanced with respect to the rotational axis. In such a way the dynamic imbalance of the wheel due to localized mass increases at the valve and at a possible joint is reduced or eliminated.
Claims15
A spoked bicycle wheel comprising a hub, a rim and a set of spoke connections connecting the hub and the rim, wherein said set comprises at least one spoke connection of a different mass at least than the remaining spoke connections in a sub-set of spoke connections regular with respect to the wheel's axis of rotation, each spoke connection comprises a spoke and a removable connection element at a first end of said spoke for removable connection with the rim or with the hub, the spoke of at least one spoke connection having a different mass than the spokes of other spoke connections, the masses of the set of spoke connections as a whole are imbalanced with respect to the wheel's axis of rotation.
A spoked bicycle wheel comprising a hub, a rim comprising a joint zone, a plurality of spoke connections that connect the hub and the rim, and a valve fitted to the rim essentially diametrically opposite the joint zone, a mass of the valve being less than a mass of the joint zone, wherein the spoke connections comprise a pair of spoke connection of increased mass with respect to the remaining spoke connections, arranged adjacent to the valve at either side thereof.
A spoked bicycle wheel comprising a hub, a rim and a plurality of spoke connections that connect the hub and the rim, wherein the spoke connections comprise at least one spoke connection of increased mass with respect to the remaining spoke connections arranged to counteract an imbalance with respect to the wheel's axis of rotation, said imbalance resulting from at least one localized mass increase of the rim, and wherein a spoke of said at least one spoke connection of increased mass comprises first and second ends, and an intermediate portion having a greater cross-sectional area than its end portions.
