    摘要： The invention includes a method for manufacturing a cycle wheel rim having, in radial cross section, two lateral flanges and a bridge, the rim having an outer surface facing outward of the rim and defined by the bridge and by at least a portion of the flanges. The manufacturing method includes the following: extruding a section; bending the section; assembling the ends of the hoop formed from the section by joining one to the another; drilling holes in the bridge for fastening the spokes; machining the entire outer surface in a radial plane and on at least a portion of the circumference of the rim.

    摘要： Skewer for tightening a cycle wheel to the cycle frame, such skewer including a first end having a threaded portion cooperable with a female thread of a first frame portion, and a second end having axial abutment mechanisms for contacting a second frame portion, as well as drive mechanisms to enable a user to alternately exert a tightening torque or a loosening torque. A torque limiting mechanism operational in the tightening direction is positioned between the drive mechanisms and the rod. The skewer further includes a braking device to increase the torque required to initiate the rotation of the drive mechanisms in the loosening direction. The braking device includes two mutually contacting friction surfaces when the axial abutment mechanisms are in contact with the second frame portion. When the torque limiting mechanism is operational, the braking device becomes non-operational because the friction surfaces are no longer in mutual contact.

    摘要： A skewer for fixing a wheel to a cycle-type vehicle, comprising a rod extending along a longitudinal axis, a first end that includes structural elements that cooperate with the vehicle frame, and a second end that includes structural elements configured to cooperate with a device exerting a tightening torque, in which the rod includes a groove extending along the longitudinal axis over a first length, an element having a variable diameter and a second length, the second length being less than the first length, is received in the groove so as to be translationally movable along the longitudinal axis, and an elastic biaser longitudinally constrains the variable diameter element towards the second end. The variable diameter element is a split tubular ring whose diameter in the free state is greater than the maximum outer diameter of the rod; it is longitudinally constrained by a spiral spring, and a distribution ring is interposed between the spring and the variable diameter element.
