Abstract
A rim for cycle wheel, provided to receive a tire and having in transverse cross-section two lateral wings forming the two lateral sides of the rim. The two lateral sides are joined at their base by a lower bridge and in their median portion by an upper bridge, so as to produce towards the tip of the wings an annular groove for receiving the tire. The rim has a rectangular global shape in cross-section. The lower bridge has a thickness less than about 0.7 millimeters.

A rim for a cycle wheel adapted to have a tire mounted thereon, said rim comprising:
- a pair of lateral sides forming, in transverse cross section, a pair of lateral wings, each of said sides having a lower end and an upper end;
- a lower bridge joining said sides at said lower ends to form a base having a predetermined width;
- an upper bridge joining said sides at respective locations between said upper and lower ends;
- said upper ends projecting upwardly from said upper bridge and forming, with said upper bridge, an annular groove for receiving the tire;
- said pair of lateral sides, said upper bridge, and said lower bridge form a substantially rectangular shape in transverse cross section;
- and
- said lower bridge has a thickness of less than about 0.7 millimeters over at least a major portion of said predetermined width of said lower bridge.
A rim for a cycle wheel adapted to have a tire mounted thereon, said rim comprising:
