Abstract
The crankset (1) includes two cranks (2) that extend in opposite directions on both sides of a crankset shaft (3), whereby each crank (2) is connected to the 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 the crankset shaft (3) and the pedal shaft (5). The housing (4) is combined with elements (11, 12) for securing the pedal shaft (5) inside the housing (4). A positioning tip (7) is secured in an eccentric manner to the free end of the pedal shaft (5), and the positioning tip (7) is able to be accommodated in the housing (4) of the crank (2) in different angular positions so as to modify the distance between centers (L).
