A spoked bicycle wheel is presented having at least one intraspoke zone with a reduced average wall thickness to reduce or eliminate the dynamic imbalance of the wheel resulting from localized mass increases at the valve and at a possible joint.

Rim for a spoked bicycle wheel, wheel and manufacturing method

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.

Bicycle wheel balanced by spoke connections of different mass

An element for the attachment of a spoke in a bicycle wheel at a seat hole has a body, an axial hole, and can engage a tool. The body is of greater transverse size than a seat hole, and abuts the seat hole at a first end of the body. The axial hole extends from the first end in the body and engages a spoke. The element engages a tool at a second end of the body opposite the first end. Finally, the maximum transverse size of said body is defined by side surface portions of said body other than the area of the second end that engages the tool.
