Claim:
A bicycle rim comprising a first, a second, and a third layer of composite material comprising structural fibers incorporated in a polymeric material, the first and second layers run parallel with each other at respective portions thereof to form a first wall of the rim, and diverge from each other at respective portions thereof, the second and the third layers run parallel with each other at respective portions thereof to form a second wall of the rim, and diverge from each other at respective portions thereof, and the third and first layers run parallel with each other at respective portions thereof to form a third wall of the rim, and diverge from each other at respective portions thereof, the diverging portions of the first, second and third layers each define a respective boundary of an enclosed space where the first, second, and third walls of the rim meet, the enclosed space enclosing a circumferentially extending reinforcement element of unidirectional structural fibers.
