Abstract
A rim for a bicycle wheel with tubeless tire comprises a radially inner peripheral wall, a radially outer peripheral wall, two circumferential side walls which connect the inner and outer peripheral walls and form two ribs which extend beyond the outer peripheral wall, for anchorage of a tubeless tire. The inner and outer peripheral walls have two holes facing one another, within which an intermediate tubular element is mounted, connected to which is a valve body of a standard type normally used for bicycle wheels provided with inner tubes.
