Abstract

The technical field of the invention pertains to the manufacture of bicycles. A bicycle crankset is described, wherein each arm of the crankset has a fixed portion (14) mounted to one end (32) of a drive shaft (31) of a chainwheel (3) which is rotatable about a horizontal axis (5), and each arm has a radially translatable portion (15) receiving a freely rotatable pedal (8); said crankset further comprises a cam (10) mounted to the frame, two rollers (12, 13) being mounted so as to roll on the edge (11) of the cam and to be freely rotatable about respective mutually parallel axes (19, 20) in relation to said movable portion (15) of the arm. In accordance with the invention, an axis (23) rotating with said arms in a plane perpendicular to the rotation axis (5) of the crankset shaft, and substantially following the path of axes (19 and 20) within said plane and the path of said axis (5), forms an angle (26) relative to the longitudinal axis (7) along which the crankarm extends (14, 15).
