Bicycle wheel

A bicycle wheel, comprising:

• a central portion;
• a plurality of first spoke portions extending outwardly from said central portion with each of said first spoke portions having a first inner end coupled to said central portion, a first outer end, and a first middle section located between said first inner and first outer ends, said first middle section having a first radial stiffness having a first bent segment to decrease radial stiffness of said wheel;
• a plurality of second spoke portions extending outwardly from said central portion with each of said second spoke portions having a second inner end coupled to said central portion, a second outer end, and a second middle section located between said second inner and second outer ends, said second middle section having a second radial stiffness that is different from said first radial stiffness of said first spoke portions;
• and
• an annular rim portion having an inner peripheral surface coupled to said outer ends of said first spoke portions and an outer peripheral surface forming a tire receiving surface thereon.

A bicycle wheel, comprising:

• a central portion;
• a plurality of spoke portions extending outwardly from said central portion with each of said spoke portions having an inner end coupled to said central portion and an outer end;
• an annular rim portion having an outer peripheral surface forming a tire receiving recess thereon, first and second annular side surfaces coupled to said outer annular surface and an inner peripheral surface coupled to said outer ends of said spoke portions, said outer ends of said spoke portions being circumferentially spaced from adjacent said outer ends of said spoke portions;
• and
• a plurality of rib portions extending from said inner peripheral surface of said annular rim portion between at least some of said spoke portions, each of said rib portions having a circumferential dimension extending between its ends, a radial dimension and an axial thickness, said radial dimension of each of said rib portions increasing in length as each of said rib portions extend from said ends to a middle rib section.

A bicycle rim, comprising:

• an outer annular surface forming a tire receiving surface thereon;
• first and second annular side surfaces coupled to said outer annular surface and located radially inwardly said outer annular surface;
• an inner peripheral surface located radially inwardly of said first and second annular side surfaces and coupling said first and second annular side surfaces together, said outer peripheral surface, said first and second annular side surfaces and said inner peripheral surface forming an annular body portion;
• a plurality of circumferentially arranged spoke attachment points formed on at least one of said inner and side surfaces;
• and
• a plurality of rib portions extending from said inner peripheral surface between at least some of said spoke attachment points, each of said rib portions having a circumferential dimension extending between its ends and a radial dimension, said radial dimension of each of said rib portions increasing in length as each of said rib portions extend from said ends to a middle rib section.
