A cycle wheel rim adapted to receive an open tire. The rim has a U-shaped radial cross section, with two sidewalls located on opposite sides of a median plane of the rim, and a lower bridge connecting the sidewalls. An upper bridge connects the sidewalls to form a closed contour. The upper bridge includes a median zone extending on opposite sides of the median plane. In the median zone and on a circumferential portion of the rim greater than or equal to 50% of its circumference, a reduced thickness of the upper bridge is less than 0.75 mm, or in an alternative embodiment, less than 0.65 mm.
