An element for the attachment of a spoke in a bicycle wheel at a seat hole has a body, an axial hole, and can engage a tool. The body is of greater transverse size than a seat hole, and abuts the seat hole at a first end of the body. The axial hole extends from the first end in the body and engages a spoke. The element engages a tool at a second end of the body opposite the first end. Finally, the maximum transverse size of said body is defined by side surface portions of said body other than the area of the second end that engages the tool.

The invention claimed is: 1. An element for the attachment of a spoke in a bicycle wheel at a seat hole, the element comprising: a body of greater transverse size than that of the seat hole for abutment about the seat hole at a first end of the body; an axial hole extending from the first end in said body, having means for engagement with a spoke and an undercut annular seat in said axial hole of the body, wherein said axial hole has an inner threading extending for at least one axial portion thereof; a plastically deformable annular element housed in the undercut annular seat; and surface tool engagement means at a second end of said body opposite said first end; wherein the maximum transverse size of said body is defined by side surface portions of said body other than tool engagement surfaces. 2. The spoke attachment element of claim 1 wherein said plastically deformable annular element comprises an inner threading contiguous and identical to the threading of the axial hole. 3. An element for the attachment of a spoke in a bicycle wheel at a seat hole, the element comprising: a body of greater transverse size than that of the seat hole for abutment about the seat hole at a first end of the body, an axial hole extending from the first end in said body, having means for engagement with a spoke, surface tool engagement means at a second end of said body opposite said first end, and a brass for abutment about the seat hole, removably associated with the first end of the body, wherein the maximum transverse size of said body is defined by side surface portions of said body other than tool engagement surfaces. 4. The spoke attachment element of claim 3 wherein the abutment brass is shaped like a bored spherical cap. 5. An element for attachment of a threaded end of a spoke in a bicycle wheel at a seat hole, having a body comprising: an abutment surface for holding at least one portion of the body at the seat hole, an axial hole having an inner threading extending for at least a portion of its length, an undercut annular seat in said axial hole, and a plastically deformable annular element housed in said annular seat and having a hole coaxial with the axial hole, wherein said undercut annular seat is in an axially intermediate position of the body. 6. The spoke attachment element of claim 5 wherein the plastically deformable annular element comprises an inner threading contiguous and identical to the threading of the axial hole. 7. The spoke attachment element of claim 5 wherein said undercut annular seat is in an axially intermediate position of said inner threading. 8. The spoke attachment element of claim 5 wherein said abutment surface is an end surface of said body. 9. The spoke attachment element of claim 5 wherein said body comprises a head and a shank, the fitting surface between head and shank being said abutment surface. 10. The spoke attachment element of claim 9 wherein said undercut annular seat is in said head portion of the spoke attachment element. 11. The spoke attachment element of claim 5 wherein said abutment surface has the shape of a spherical cap. 12. The spoke attachment element of claim 5 further comprising a bored spherical cap brass at said abutment surface. 13. An element for the attachment of a spoke in a bicycle wheel at a seat hole, the element comprising: a body of greater transverse size than that of the seat hole for_abutment about the seat hole at a first end of the body, an axial hole extending from the first end in said body that is configured to engage a spoke, a second end of the body, opposite the first end, that is configured to engage a tool, a semi-spherical shaped brass for abutment about the seat hole, removably associated with the first end of the body, wherein the maximum transverse size of said body is defined by side surface portions of said body other than tool engagement surfaces. 14. An element for attachment of a threaded end of a spoke in a bicycle wheel at a seat hole, having a body comprising: an abutment surface for holding at least one portion of the body at the seat hole, an axial hole having an inner threading extending for at least one axial portion of its length, an undercut annular seat in said axial hole, and a plastically deformable annular element housed in said annular seat and having a hole coaxial with the axial hole, wherein said undercut annular seat is in an axially intermediate position of the body. 15.
