Patent ID: 7562891

Claim:
A cycle crankset, comprising: two cranks ( 2 ) that extend in opposite directions on both sides of a crankset shaft ( 3 ), whereby each crank ( 2 ) is connected to said crankset shaft ( 3 ) at one of its ends and has, at its opposite end, a housing ( 4 ) that can accommodate a free end of a pedal shaft ( 5 ) by defining a distance between centers (L) between said crankset shaft ( 3 ) and said pedal shaft ( 5 ), whereby said housing ( 4 ) is combined with means ( 10 to 12 ) for securing the pedal shaft ( 5 ) inside said housing ( 4 ); and a positioning tip ( 7 ) secured in an eccentric manner to said free end of said pedal shaft ( 5 ), whereby said positioning tip ( 7 ) is able to be accommodated in said housing ( 4 ) of the crank ( 2 ) in different angular positions so as to modify said distance between centers (L), whereby said angular positions are defined by flat surfaces ( 8 ; 16 ) placed uniformly on a periphery of said positioning tip ( 7 ) and are able to work with at least one flat surface ( 9 ; 17 ) that is provided inside said housing ( 4 ) of the crank ( 2 ), wherein a peripheral surface of said positioning tip ( 7 ) is conical as well as the surface of the wall of said housing ( 4 ) of the crank ( 2 ) so as to be complementary, and thereby said flat surfaces ( 8 ; 16 ) are tilted toward the end of said positioning tip, and wherein said at least one flat surface ( 9 ; 17 ) of said housing ( 4 ) has a same slope.
