Abstract
A spoked bicycle wheel having a rim at least partially comprised of a composite material. The rim has at least one spoke attachment chamber with a plurality of spoke attachment holes. The wheel has a plurality of spokes coupled with the rim and a spoke attachment element partially inserted in a respective spoke attachment hole. The wheel includes a holding element that prevents the movement of said spoke attachment element along a radially outer direction. The spoke attachment element has a holding surface configured for abutment against the holding element.
Claims15
A spoked bicycle wheel, comprising:
- a rim made at least partially from composite material and having at least one spoke attachment chamber provided with a plurality of spoke attachment holes,
- a plurality of spokes coupled with the rim at said spoke attachment holes,
- a spoke attachment element partially inserted in said spoke attachment hole,
- wherein said wheel comprises at least one holding element configured to prevent movement of said spoke attachment element along a radially outer direction and in that said spoke attachment element comprises a holding surface configured to operate in abutment against said at least one holding element.
A spoke attachment element for a spoked bicycle wheel, comprising a stem configured to be inserted in a spoke attachment hole of a rim of the wheel and an enlarged head configured to abut against the rim, or an insert in abutment against the rim at said spoke attachment hole,
- wherein said enlarged head or said stem comprises a holding surface configured to abut against at least one holding element defined in said rim or in said insert to prevent movement of the spoke attachment element along a radially outer direction.
An adjustment tool for adjusting tension in a spoke of a spoked bicycle wheel, comprising an elongated body extending along a longitudinal axis (Y) and having a central longitudinal cavity configured to house an end portion of the spoke and a longitudinal through slit configured to allow the housing of said end portion of the spoke in said longitudinal cavity,
- wherein said elongated body comprises a grip portion and a shaped end portion extending along said longitudinal axis (Y) and configured to couple with a stem of a spoke attachment element, and said shaped end portion has an outer bulk, defined on a plane perpendicular to the longitudinal axis (Y) of the elongated body, smaller than that of said grip portion and smaller than a diameter of a spoke attachment hole provided in a rim of the wheel and in which said stem is inserted.
A method for assembling a spoked bicycle wheel, comprising the steps of:
- making a rim having a plurality of spoke attachment holes;
- inserting a spoke attachment element in the rim through an inflation hole or an auxiliary hole specifically provided in the rim;
- bringing said spoke attachment element at a respective spoke attachment hole;
- partially inserting said spoke attachment element in said spoke attachment hole;
- and
- coupling a spoke with said spoke attachment element;
- wherein the step of partially inserting said spoke attachment element in said spoke attachment hole comprises bringing a holding surface defined in said spoke attachment element into a radially inner position with respect to a holding element defined in said wheel so that a movement of said spoke attachment element along a radially outer direction is prevented by an abutment between said holding element and said holding surface.
