摘要： A nipple for spoked wheels of the tubeless type comprises a first and a second shoulder which are formed on a rod with a blind axial hole which is internally threaded at an end of the rod which is distal from the opening of the axial hole and in a zone of the rod which is proximal with respect to the opening, respectively. A first recess for a sealing ring is formed on the rod behind the first shoulder and at least a second recess for a second sealing ring is formed on the rod between the first recess and the second shoulder.

摘要： A nipple for spokes of spoked wheels includes a rod with an axial development, a threaded hole which is formed axially in the rod, the thread of the hole defining a root diameter and a crest diameter, a head which is widened with respect to the rod and a deformable insert which is inserted in a seat which is axially aligned with the hole and which is constructed in an axially intermediate position thereof. The insert, at least when it is inserted in the seat, has a passage for a threaded spoke end, the internal diameter of which is less than the root diameter of the thread of the hole so as to interfere with the thread of the spoke when it is screwed into the threaded hole.
