Claim:
A roller peg ( 1 ) comprising: a. a mandrel ( 100 ) having a mandrel surface ( 110 ), a mandrel first end ( 120 ) and a mandrel second end ( 150 ); a flange ( 130 ) is proximal the mandrel first end ( 120 ); mandrel bore means ( 160 ), comprising a bore, from the mandrel second end ( 150 ) toward and proximal the mandrel first end ( 120 ); a socket provided by a mandrel socket cap ( 122 ) at the mandrel first end ( 120 ); the mandrel socket cap ( 122 ) forms a socket for wrench or socket head engagement for wrench rotation of the mandrel ( 100 ) for thread engagement of a bicycle threaded axle ( 180 ) with either or both the mandrel bore ( 160 ) and the nut ( 300 ); b. a cover bearing ( 200 ) having a cover bearing first end ( 220 ) and a cover bearing second end ( 250 ); a cover bearing aperture ( 260 ), having a cover bearing aperture inside surface ( 270 ), from the cover bearing first end ( 220 ) to the cover bearing second end ( 250 ); the cover bearing ( 200 ) has a cover bearing outer surface ( 265 ) and is primarily circular in cross-section; c. the cover bearing aperture ( 260 ) is sized to rotatably receive, at the cover bearing aperture first end ( 220 ), the mandrel ( 100 ) at the mandrel second end ( 150 ); the cover bearing aperture inside surface ( 270 ) rotatably and bearingly receives the mandrel ( 100 ) at the mandrel surface ( 110 ); a mandrel axis ( 170 ) is centrally positioned from the mandrel first end ( 120 ) to the mandrel second end ( 150 ) and from the cover bearing first end ( 220 ) to the cover bearing second end ( 250 ); d. the cover bearing ( 200 ), proximal the cover bearing first end ( 220 ), is recessed forming a cover bearing aperture shoulder ( 230 ) proximal the cover bearing outer surface ( 265 ) and extending to the cover bearing inside surface ( 270 ) forming a bearing surface sized to rotatably and bearingly receive the flange ( 130 ); e. a cover bearing hex recess ( 255 ) is formed at the cover bearing second end ( 250 ); the cover bearing hex recess ( 255 ) is formed to rotatably and bearingly receive a mandrel second end washer ( 157 )-or fixedly receive said nut ( 300 ); the nut ( 300 ) having a nut aperture ( 320 ) which is smooth or threaded; the nut ( 300 ) having a drop out key ( 340 ); f. the nut aperture ( 320 ), the cover bearing aperture ( 260 ) and the mandrel bore ( 160 ) are concentric with the mandrel axis ( 170 ); the drop out key ( 340 ) is generally planar extending outwardly from the nut ( 300 ) distal to the nut aperture ( 320 ) and generally parallel with the mandrel axis ( 170 ) and orthogonal to the nut ( 300 ); g. the nut aperture ( 320 ) and the mandrel second end washer ( 157 ) rotatably receiving a bicycle threaded axle ( 180 ); the mandrel bore ( 160 ) is threaded and fixedly receives the bicycle threaded axle ( 180 ).
