Abstract
A bicycle rim and/or wheel are provided. The bicycle rim and/or wheel includes a single wall formed into the bicycle rim. The wall is formed of composite material having a spoke attachment portion and a tire attachment portion formed therein. The composite material may include at least two different materials, or fibers used as reinforcement material, forming layers of a thickness of the rim.
Claims19
A bicycle rim, comprising:
- a single wall formed into the bicycle rim, the wall formed of composite material having a spoke attachment portion and a tire attachment portion formed therein,
- wherein the single wall is formed in a radially asymmetric configuration such that in an un-tensioned state a first radial height of a first bead shelf of a first side of the rim is different than a second radial height of a second bead shelf of a second side of the rim, and in a tensioned state the single wall is deformed, wherein attachment of the spokes causes the first radial height to become the same as the second radial height.
A bicycle rim, comprising:
- a single wall formed into the bicycle rim, the wall formed of composite material having a spoke attachment portion and a tire attachment portion formed therein, the composite material formed of layers providing a thickness of the rim, wherein the wall is formed in a radially asymmetric configuration such that in an un-tensioned state a first radial height of a first bead shelf of a first side of the rim is different than a second radial height of a second bead shelf of a second side of the rim, and in a spoke induced tensioned state the single wall is deformed such that the first radial height matches the second radial height.
A bicycle wheel, comprising:
- a rim formed from composite materials, the rim formed as a single wall having a spoke attachment portion and a tire attachment portion, wherein the single wall is formed in a radially asymmetric configuration such that in an un-tensioned state a first radial height of a first bead shelf of a first side of the rim is different than a second radial height of a second bead shelf of a second side of the rim, and in a tensioned state the single wall is deformed such that a difference between the first radial height and the second radial height is reduced;
- a central hub for rotational attachment to a bicycle frame;
- and
- a plurality of spokes extending from the tire attachment portion of the rim and attached to the hub.
