Abstract: A clipless pedal device (1) for securing a first securing arrangement provided on the pedal with a second securing arrangement fixed under the sole of the cycling shoe, includes an attachment arrangement (8). The attachment arrangement (8) includes at least one moving part that is prestressed into the attachment position by an elastic element (5a, 5b). The elastic element (5a, 5b) includes a straight oblong part constituting a torsionally (T) stressed element.

Abstract: The bicycle crankset includes a bottom bracket axle, two cranks and a chainring carrier bearing first and second different toothed chainrings. The chainring carrier has the shape of a star, of which each arm is provided with a mounting hole aligned with a mounting hole in the first and second chainrings respectively. These holes accommodate elements for fastening chainrings to the chainring carrier, and they are arranged on a first circle with a predetermined diameter. Each arm of the chainring carrier is provided with a second mounting hole arranged on a second circle with a diameter that has been reduced relative to the first circle to match the chainring carrier to two other toothed circular chainrings with a size that is respectively reduced relative to the first and second chainrings and of which the mounting holes are located on the second circle.

Abstract: This automatic bicycle pedal comprises a pedal body (2) equipped at a first end (5) with first attachment means (7) and at a second end (6) with second attachment means (10), an elastically deformable lever (8) bearing the second attachment means and capable of being deformed between a first position of holding a cleat fixed to the underside of a shoe between the first and second attachment means, and a deformed second position allowing the cleat to be attached and detached in respect of attachment and detachment movements. The deformable lever comprises at least one first deformable zone (12) that can be deformed during attachment and detachment movements and at least one second deformable zone (13) that can be deformed during one of the said attachment and detachment movements, the said first and second zones having different stiffnesses.

Abstract: The measuring device is intended to measure forces on a bicycle pedal (1) mounted to rotate on a pedal spindle (2) fixed at the free end of a crankset crankarm (6). The device includes force sensors positioned on the pedal spindle and able to detect the force directed perpendicularly to the pedal spindle and to supply a signal dependent on the force detected, and electronic elements able to process the signals received from the sensors. Some of the electronic elements are incorporated in an electronic card (23) powered by a stand-alone energy source and to which is fixed a male connecting member (24) able to pass through a fixing hole (5) of the pedal spindle (2) on the crankarm (6) in order to cooperate with a female connecting member provided in the end of the pedal spindle. The electronic card forms with the male connecting member an easily detachable assembly.

Abstract: The headset rotationally connects a fork pivoting tube (1) to a steering tube (2) of a cycle frame. It includes a lower roller bearing (3), an upper roller bearing (4), and an element (9, 10) for axially locking the lower and upper roller bearings (3, 4) against a lower or upper end of the steering tube (2). The mechanism for axial locking includes a first element of axial locking that consists of a circular groove (9) that is provided on the outside face of the pivoting tube (1) that works with a second element of axial locking that consists of a rib (10) with an essentially matching shape that is provided on an elastically deformable annular element (11) in a direction that is perpendicular to the axis (A-A) of the pivoting tube (1) and placed above the upper roller bearing (4) so as to exert a thrust against the latter.

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).
